• What is the cause and solution for SAP error message /SEHS/BA_MISC1718 - Function &: Changing parameter & does not have the correct type (pool) ?

  The SAP error message /SEHS/BA_MISC1718 Function &: Changing parameter & does not have the correct type (pool) typically indicates that there is a mismatch in the expected data type for a changing parameter in a function module or method. This error is often encountered in the context of ABAP programming, particularly when dealing with function modules that are expected to receive certain types of parameters.
  Cause:
  
  Type Mismatch: The changing parameter being passed to the function does not match the expected data type defined in the function module. For example, if the function expects a certain structure or data type (like a specific table type or a simple data type) and receives a different one, this error will occur.
  Incorrect Declaration: The function module may have been incorrectly declared or modified, leading to a mismatch in the expected parameter types.
  Inconsistent Data Types: If the function is being called from different places in the code, and the data types used in those calls are inconsistent, it can lead to this error.
  
  Solution:
  
  Check Function Module Definition: Review the definition of the function module to ensure that the changing parameter is correctly defined with the expected data type.
  Verify Calling Code: Look at the code where the function is being called. Ensure that the variable being passed as the changing parameter matches the expected type. If necessary, convert or cast the variable to the correct type.
  Use Correct Data Types: Make sure that the data types used in the calling program are consistent with those defined in the function module. If the function expects a specific structure or table type, ensure that you are passing the correct type.
  Debugging: Use debugging tools in SAP to step through the code and inspect the values and types of the parameters being passed to the function. This can help identify where the mismatch is occurring.
  Documentation: Refer to the SAP documentation or the function module documentation for details on the expected parameter types.
  
  Related Information:
  
  ABAP Data Types: Familiarize yourself with the different data types in ABAP, including elementary types, structured types, and table types.
  Function Module Documentation: Each function module in SAP has documentation that specifies the expected parameters. Use transaction SE37 to view the function module and its parameters.
  SAP Notes: Check for any relevant SAP Notes that might address known issues or provide additional guidance related to this error message.
  
  By following these steps, you should be able to identify and resolve the issue causing the error message /SEHS/BA_MISC1718.
