• What is the cause and solution for SAP error message OO390 - Methods for CDS table functions cannot be tested and were removed ?

  The SAP error message OO390 indicates that methods for Core Data Services (CDS) table functions cannot be tested and have been removed. This error typically arises when you attempt to test a CDS table function in the ABAP Development Tools (ADT) or in the ABAP Workbench, but the system does not support testing for certain types of CDS table functions.
  
  Cause:
  
  CDS Table Function Limitations: CDS table functions are designed to return a table-like structure and may include complex logic that cannot be executed in a testing environment. The error suggests that the specific CDS table function you are trying to test has characteristics that prevent it from being executed in the test environment.
  Incompatibility with Testing Framework: The testing framework in SAP may not support the execution of certain methods or functions defined in CDS views or table functions, especially if they involve parameters or complex logic.
  
  
  Solution:
