C_TB1300_90 Exam Guide: Scope, Status, Skills, and a Practical Study Plan
C_TB1300_90 was identified by SAP as the SAP Business One Development Associate exam, focused on development with the SAP Business One Software Development Kit. It is relevant to developers and partners who work on extensions or integrations around SAP Business One. The most important decision comes first: SAP announced that this exam would be withdrawn at the end of June 2019, so candidates should verify current recognition and replacement options through SAP Learning before investing in an exam-specific study plan. This guide separates confirmed SAP content from sensible preparation recommendations.
Is C_TB1300_90 still an exam you can schedule?
Treat C_TB1300_90 as a historical exam unless SAP Learning or another current SAP channel confirms a valid registration route. SAP announced that the SAP Business One Development Associate exam C_TB1300_90 would be withdrawn at the end of June 2019, and described it as more than five years old at the time of that announcement.
That status changes the preparation decision. Do not begin by purchasing an exam voucher, searching for a test appointment, or relying on an old preparation page. First check SAP’s current SAP Business One certification overview and look for a current successor, learning path, or registration process. The current certification overview is available through SAP Learning: https://learning.sap.com/certifications/sap-certified-associate-sap-business-one.
The withdrawal announcement also said that SAP was creating new self-study SAP Business One development materials to replace the withdrawn certification content. This means older C_TB1300_90 material can still help explain the historical SDK scope, but it should not automatically be treated as the current certification blueprint.
What professional capability did the exam represent?
The exam represented SAP Business One development rather than general end-user operation. SAP associated C_TB1300_90 with the Development Associate designation, while the related TB1300 material describes development with the SAP Business One Software Development Kit. Prepare around extension and integration concepts, not around routine navigation through business transactions.
SAP states that the SDK enables partners to extend SAP Business One through APIs and other features. That gives the exam its practical center: understanding how an external or partner-built solution can work with SAP Business One data and functionality while respecting the platform’s architecture.
A useful audience definition is therefore specific. The historical scope is most relevant to developers, technical consultants, and partner personnel who need to reason about SAP Business One extensions, programmatic access, and integration choices. It is less suitable as a standalone study target for someone seeking only functional configuration knowledge.
What should a candidate be able to explain?
A candidate studying the historical scope should be able to distinguish the platform’s development interfaces, explain where business data is held, and select an integration approach based on the client or application context. Those are study outcomes inferred from SAP’s TB1300 development material, not a replacement for a current official exam blueprint.
Build explanations around four questions: what component is being accessed, which interface exposes it, where the consuming application runs, and what kind of SAP Business One business data is required. This framework is more useful than memorizing isolated product names because it forces an architectural decision.
Use the official TB1300 material as the technical reference for this scope: https://help.sap.com/doc/saphelpiis_hc_b1_image_repository_development_training_basic_b1_90_tb1300_01_pdf/9.0/en-US/B1_90_TB1300_01.pdf.
Which technical areas deserve study time?
Prioritize the SDK’s role, the Data Interface API, the DI Server, the two-layer architecture, and the relationship between SAP Business One data and the database platform. SAP’s material supports these as core development topics. It does not provide a current percentage-based blueprint for C_TB1300_90 in the supplied research.
Start with architecture before interface details. SAP describes SAP Business One as using a two-layer architecture with data centrally stored in a Microsoft SQL Server or SAP HANA database. That fact matters because an integration design must account for the application layer, the central data store, and the approved programmatic access path rather than treating the database as the entire application.
Then study interface purpose. SAP identifies the Data Interface API as a way to access SAP Business One business data and states that most business objects are exposed through it. Separately, SAP states that the DI Server lets partners use SAP Business One data in a browser without installing an SAP Business One component on the client or web application server.
Finally, connect the interfaces to the SDK. SAP states that the SAP Business One SDK provides programmatic interfaces based on COM and enables partners to extend SAP Business One using APIs and other features. The goal is not to recite labels; it is to explain why a particular interface belongs in a particular solution.
How should the architecture be organized in your notes?
Create one diagram with the SAP Business One application, the central database, the SDK interfaces, and the consuming client or web application. Label each arrow with its purpose. This makes the two-layer architecture and the distinction between local component use and browser-oriented access easier to recall under pressure.
Do not collapse the Data Interface API and DI Server into one interchangeable term. The supplied SAP material identifies both as routes for working with SAP Business One data, but it gives the DI Server a specific browser-access context. Your notes should preserve that distinction and record the deployment implication beside it.
What does the COM statement mean for preparation?
SAP’s statement that the SDK provides programmatic interfaces based on COM is a platform fact to understand, not a reason to memorize undocumented implementation details. Study what an interface enables, what application context it serves, and how it fits into an extension design.
A practical exercise is to write a short design choice for a desktop-style partner tool and a browser-based application. For each, state the access requirement, the relevant SDK concept, and the reason the alternative is less suitable. Keep the exercise conceptual unless you have an authorized development environment and current technical documentation.
Are official exam-domain percentages available?
No verified domain percentages were supplied for C_TB1300_90. Do not publish or study from bare weight claims copied from unofficial pages. The available official material identifies the development subject area and specific SDK concepts, but it does not establish a current percentage allocation for named exam domains.
This limitation affects prioritization. Use the SAP TB1300 material and the official sample-questions PDF to identify the kinds of concepts that require review, while treating your own time allocation as a study decision rather than an official blueprint. The sample-questions document is specifically named for C_TB1300_90: https://cdn.training.sap.com/uploads/Sample_Questions_C_TB1300_90_%282%29.pdf.
If a future or replacement certification page supplies domains and percentages, record each percentage together with its exact domain label and version context. Until then, do not turn a personal estimate into an exam fact.
How should you use the official sample questions?
Use the sample questions as a diagnostic tool, not as a substitute for learning the SDK. First answer without notes, then classify every uncertain response by concept: architecture, interface purpose, deployment context, or extension behavior. The result should tell you what to revisit in the SAP material.
Read the wording carefully and explain why the correct option fits the architecture or API purpose. If you remember an answer but cannot explain the underlying choice, mark it as weak knowledge. Memorized answer patterns are especially unreliable when an old exam has been withdrawn or its supporting materials have changed.
Do not use leaked questions, exam dumps, or claims of repeated live items as a preparation method. They do not establish the current exam status, do not validate understanding, and cannot safely replace official learning content. The official PDF is useful because SAP published it for C_TB1300_90, not because sample items guarantee the live assessment.
After review, create a small error log with three fields: the concept tested, the reason your answer failed, and the source section to reread. This turns a sample-question session into a targeted study cycle instead of repeated guessing.
What is a sensible study sequence?
Follow the dependency between concepts: establish the architecture, understand the SDK’s purpose, separate the APIs, and then apply those distinctions to integration scenarios. This order prevents interface memorization without a clear model of where the interface operates.
Begin with the TB1300 development scope. Write a one-page explanation of what the SDK enables and how programmatic access supports extensions. Include the COM-based interface fact and the relationship between the application layer and central database.
Next, study the Data Interface API. Your notes should answer what it accesses, what SAP says about business-object exposure, and how that role differs from direct database thinking. Avoid adding technical claims that are not present in the official material unless you have a separate, authorized source.
Then study the DI Server in its stated context. Focus on the browser scenario and the absence of an SAP Business One component on the client or web application server, as described by SAP. Turn this into a deployment decision rather than a definition copied from a glossary.
Finish with comparison exercises. Given a business requirement, identify the data access need, the application location, the appropriate SDK concept, and the architectural reason. This is a stronger readiness check than rereading the same pages.
A four-stage roadmap
Stage one is orientation. Confirm the historical status through SAP’s announcement and check the current SAP Learning certification overview for any replacement. Save the official links and record which material is historical.
Stage two is concept building. Read the TB1300 material with a diagram open beside it. Capture only supported facts first: two-layer architecture, central database choices, COM-based programmatic interfaces, Data Interface API purpose, and DI Server browser access.
Stage three is application. Draft several original integration scenarios without pretending they are live exam questions. For each scenario, justify the interface choice and identify the architectural assumption behind it.
Stage four is verification. Use the official sample questions, review every uncertain answer, and return to the source material. If you cannot explain an answer in your own words, continue studying rather than treating a correct guess as readiness.
How should study time be allocated without a blueprint?
Allocate time according to uncertainty and dependency, not invented percentages. Spend more effort on concepts that affect several decisions, such as the difference between the Data Interface API and DI Server, than on isolated terminology.
A useful session pattern is source reading, closed-book explanation, scenario application, and error-log review. Keep the source reading short enough that most of the session tests retrieval and reasoning. Adjust the balance after each diagnostic pass rather than following a fixed schedule unsupported by an official blueprint.
Which mistakes create false confidence?
The most damaging mistake is preparing for an exam that is no longer available without first checking SAP’s current certification information. Other common errors include treating historical sample questions as a complete syllabus, confusing access methods, and studying database facts without understanding the application architecture.
Mistake one is assuming an old exam code proves current availability. The withdrawal announcement is official evidence that the code had a historical end point; it is not evidence of a present registration route. Verify before making a scheduling or payment decision.
Mistake two is treating the SDK as a single undifferentiated tool. SAP’s material names multiple interfaces and assigns them different roles. Make a comparison table with columns for purpose, consuming application context, and architectural implication.
Mistake three is reducing the subject to database access. SAP describes centrally stored data, but the development material also emphasizes APIs and SDK features. A solution that simply reaches for the database may miss the platform-level integration question being tested.
Mistake four is copying unsupported exam claims from third-party pages. Be particularly cautious with question counts, time limits, passing scores, languages, delivery methods, prices, prerequisites, and domain weights. None of those details is verified in the supplied research.
What should you verify before making a booking decision?
Verify the current certification name, whether C_TB1300_90 is accepted or replaced, the registration path, and the current preparation resources on SAP Learning. The supplied evidence confirms the historical withdrawal but does not provide current booking instructions, delivery details, price, duration, score, question count, language, or prerequisites.
Use the SAP Learning certification overview as the first current-status check: https://learning.sap.com/certifications/sap-certified-associate-sap-business-one. Compare any current listing with the historical C_TB1300_90 code rather than assuming that a similar title represents the same assessment.
If a third-party site presents a purchasable C_TB1300_90 product, treat that as a reason to verify, not as proof that SAP currently administers the exam. A product listing can describe study material without establishing official exam availability.
Before scheduling any certification assessment, confirm the official rules directly in the current SAP source. Record the date you checked and the exact certification title so that an old document does not silently become your planning authority.
How can hands-on practice remain useful without a live exam claim?
Hands-on practice should demonstrate architectural reasoning and interface selection, not imitate confidential exam content. Build small, authorized exercises that make you explain how an extension or integration would obtain SAP Business One data and why the chosen access route fits the client context.
For an architecture exercise, sketch the two layers and place the central database in the model. Explain what belongs in the application or integration layer and what should not be inferred merely from the fact that data is centrally stored.
For an API exercise, start with a business-data requirement and identify whether the scenario calls for the Data Interface API concept described by SAP. State which business object or data need is involved only when your authorized documentation supports it; do not invent object coverage beyond SAP’s statement that most business objects are exposed.
For a browser exercise, explain the DI Server requirement in plain language: the partner wants SAP Business One data available in a browser without installing an SAP Business One component on the client or web application server. This directly tests the deployment distinction supported by the official material.
If you have access to a permitted development environment, document setup assumptions, interface calls, errors, and cleanup. Keep those observations separate from exam facts. A local experiment can improve understanding, but it cannot establish what a withdrawn or replacement certification currently tests.
What should your final review sheet contain?
Your final sheet should fit the decisions the material requires: what the SDK is for, how SAP Business One is structured, what the Data Interface API provides, when the DI Server’s browser context matters, and how those concepts support partner extensions. Add source links and a short list of unresolved items to verify in current SAP Learning information.
Use a comparison grid rather than a long glossary. One row can cover the SDK’s extension role, another the Data Interface API’s business-data access, and another the DI Server’s browser-oriented access context. Add the COM fact and the database-platform choices in the architecture row.
Add a status box stating that SAP announced withdrawal of C_TB1300_90 at the end of June 2019. This prevents an old code from being mistaken for a current booking target when the notes are reused later.
Leave out unsupported operational data. A review sheet is stronger when it identifies what is unknown than when it fills gaps with copied figures or outdated claims.
What is the right next action for a C_TB1300_90 candidate?
Make verification your next action: open SAP Learning’s current SAP Business One certification overview and determine whether SAP lists C_TB1300_90, a successor, or a replacement learning route. If no current route is shown, use the historical material for technical development knowledge rather than treating it as a schedulable certification.
After status verification, download or review the official sample-questions PDF and the TB1300 material. Build the architecture diagram, create the API comparison table, and complete a diagnostic pass without notes. Those actions give you evidence about your knowledge while avoiding unsupported assumptions about the withdrawn exam.
If SAP identifies a replacement, restart your plan from that replacement’s official scope. Preserve the historical C_TB1300_90 notes only where they align with the new source. If no replacement is available, focus on transferable SAP Business One SDK understanding and do not purchase an exam-specific product based solely on the old code.
The most defensible preparation decision is therefore conditional: verify the certification first, study the official technical scope second, and schedule only when a current SAP source confirms that the assessment exists and explains its registration requirements.
Conclusion
C_TB1300_90 has a clear historical identity as the SAP Business One Development Associate exam, and SAP’s TB1300 material provides a useful technical foundation in SDK development, architecture, business-data interfaces, and browser-oriented access through the DI Server. Its announced withdrawal at the end of June 2019 makes current-status verification essential. Use the official sources to establish what remains relevant, use sample questions only for diagnosis, and base any booking decision on current SAP Learning information rather than legacy listings or unsupported exam claims.
