• What is the cause and solution for SAP error message CMX_XS102 - Parameter type &1 and reference parameter &2 are not compatible ?

  The SAP error message CMX_XS102 indicates that there is a type mismatch between a parameter and its reference parameter in a configuration or function call. This typically occurs in the context of SAP's Cross-Application (CA) or other modules where parameters are expected to be of compatible types but are not.
  Cause:
  
  Type Mismatch: The most common cause of this error is that the parameter type specified does not match the expected type of the reference parameter. For example, if a parameter is defined as an integer but is being passed a string, this error will occur.

  Data Type Changes: Changes in data types in the underlying data model or in the function module can lead to this error if the calling program has not been updated accordingly.
  
  Solution:
  
  Check Parameter Definitions: Review the definitions of the parameters involved. Ensure that the data types of the parameters match the expected types. This can be done in the ABAP Dictionary or in the function module definition.
  Update Calling Code: If you are calling a function module or method, ensure that the parameters you are passing are of the correct type. You may need to convert data types explicitly if they are not compatible.
  Debugging: Use the debugger to step through the code where the error occurs. This can help identify the exact point of failure and the values being passed.
  Consult Documentation: If you are using standard SAP functions or modules, refer to the SAP documentation to understand the expected parameter types and any changes that may have been made in recent updates.
  Testing: After making changes, thoroughly test the functionality to ensure that the error is resolved and that no new issues have been introduced.
