Also after this blog post you will be able to update the entries. “This is very useful technique which can be....
Unit tests play a big role in modern software development. Unit tests let us check parts of our code for correctness very quickly within seconds. Independence of unit tests on any external dependencies means independence on any external environments like network, file system, database etc Most of SAP developments work with database and we need....
Introduction: In this blogpost, I will try to give you brief idea about LUW (Logical Unit of Work). It is basically required time for system to complete the process of Database (DB) data modification. Either Full or Rollback all changes done in DB data. Main purpose of LUW is to ensure data consistency in system.....
When working with the Custom Code Migration app, there are some typical pitfalls. Here is a list of solutions for the most frequent questions and issues. Known Problems I want to create a cloud-to-on-premise connection and configure the RFC access control list. During the ATC run, I get an error, e.g. “Access denied for function_module_name_xyz....
SAP defines Test-Driven Development (TDD) as “a way to develop software driven by automated tests which are written earlier than the production code itself”[1] Applying this approach for AMDPs is particularly challenging since there are no built-in tools for mocking database tables within AMDPs (unlike regular ABAP classes, where cds views and database tables can....
More of an announcement rather than a blog: Drumroll for the latest in Unit Testing Frameworks, Function Modules. Function modules have always been the thorn in the side of anyone trying to write ABAP Unit Tests. The only sensible way to mock a call to a function module was to wrap the FM into a....
