• What is the cause and solution for SAP error message PFO1058 - RFC: Incorrect number of transferred fields, DDIC structure &1 ?

  The SAP error message PFO1058 indicates that there is an issue with the number of fields being transferred in a Remote Function Call (RFC) related to a Data Dictionary (DDIC) structure. This error typically arises when the structure being used in the RFC does not match the expected number of fields defined in the Data Dictionary.
  Cause:
  
  
  Mismatch in Structure Definition: The structure defined in the ABAP Dictionary (DDIC) does not match the structure being passed in the RFC call. This could be due to:
  
  Changes in the structure definition that have not been reflected in the calling program.
  The calling program is using an outdated version of the structure.
  The structure being passed has been modified (fields added or removed) but the calling program has not been updated accordingly.
  
  
  
  Incorrect Mapping: The fields being mapped in the RFC call do not correspond correctly to the fields defined in the DDIC structure.
  
  
  Data Type Issues: There may be data type mismatches between the fields in the calling program and the DDIC structure.
  
  
  Solution:
  
  
  Check Structure Definition: Verify the structure definition in the ABAP Dictionary (transaction SE11) to ensure that it matches the expected structure in the RFC call. Make sure that the number of fields and their data types are consistent.
  
  
  Update Calling Program: If the structure has been modified, update the calling program to ensure it uses the correct version of the structure. This may involve regenerating the function module or updating the data declaration in the ABAP code.
  
  
  Field Mapping: Review the field mapping in the RFC call to ensure that all fields are correctly mapped and that the number of fields being passed matches the definition in the DDIC structure.
  
  
  Testing: After making the necessary changes, test the RFC call again to ensure that the error is resolved.
  
  
  Related Information:
  
  Transaction Codes: Use transaction codes like SE11 (Data Dictionary), SE37 (Function Module), and SE80 (Object Navigator) to investigate and modify the relevant structures and function modules.
  Debugging: If the issue persists, consider using the debugger to trace the RFC call and inspect the data being passed to identify discrepancies.
  Documentation: Review any documentation related to the RFC interface to ensure that all changes are properly documented and communicated to relevant stakeholders.
  
  By following these steps, you should be able to resolve the PFO1058 error and ensure that the RFC call functions correctly.
