• What is the cause and solution for SAP error message /IWBEP/CM_V4_MED124 - Conversion exit '&1' not found ?

  The SAP error message /IWBEP/CM_V4_MED124 Conversion exit '&1' not found typically occurs in the context of SAP Gateway or OData services when the system is unable to find a specified conversion exit for a field. This can happen during data processing, especially when converting data types or formats.
  Cause:
  
  Missing Conversion Exit: The specified conversion exit (indicated by &1 in the error message) is not defined in the system. This could be due to a missing or incorrectly configured conversion routine.
  Incorrect Field Mapping: The field in the OData service may be mapped to a data type that requires a conversion exit that does not exist.
  Custom Development Issues: If there are custom fields or enhancements, the conversion exit may not have been implemented correctly.
  Transport Issues: If the system has recently undergone a transport, the conversion exit may not have been included or activated in the target system.
  
  Solution:
  
  Check Conversion Exits: Verify if the conversion exit exists in the system. You can do this by checking the relevant data element in transaction SE11 (Data Dictionary) or SE80 (Object Navigator).
  Create or Adjust Conversion Exit: If the conversion exit is missing, you may need to create it or adjust the existing one. This can be done using transaction SE37 (Function Modules) to create a new function module that serves as the conversion exit.
  Review OData Service: Check the OData service definition in transaction /IWFND/MAINT_SERVICE to ensure that the field mappings are correct and that they reference valid conversion exits.
  Debugging: Use transaction SE80 or SE37 to debug the OData service and identify where the error is occurring. This can help pinpoint the exact field or mapping causing the issue.
  Transport Check: If the issue arose after a transport, ensure that all necessary objects, including conversion exits, were transported correctly.
