• What is the cause and solution for SAP error message /AIF/WET_GEN_STR007 - Function module &1 includes not supported predefined data types ?

  The SAP error message /AIF/WET_GEN_STR007 indicates that a function module is using predefined data types that are not supported by the Application Interface Framework (AIF). This typically occurs when you are trying to use a function module that has parameters defined with data types that AIF cannot process.
  Cause:
  
  Unsupported Data Types: The function module includes parameters with data types that are not compatible with AIF. Common unsupported data types include certain complex structures, deep structures, or specific SAP data types that AIF does not recognize.
  Incompatibility with AIF: AIF has specific requirements for the data types it can handle, and if the function module does not adhere to these requirements, the error will be triggered.
  
  Solution:
  
  Review Function Module: Check the function module in question and identify the parameters that are using unsupported data types. You can do this by navigating to the function module in transaction SE37 or SE80.
  Modify Data Types: If possible, modify the function module to use supported data types. This may involve changing complex structures to simpler ones or using standard data types that AIF can process.
  Create Wrapper Function Module: If modifying the original function module is not feasible, consider creating a wrapper function module that calls the original function module but uses supported data types for its parameters.
  Consult Documentation: Refer to the SAP AIF documentation to understand which data types are supported and any specific guidelines for creating interfaces.
  Testing: After making changes, thoroughly test the function module to ensure that it works correctly with AIF and that the data is processed as expected.
