• What is the cause and solution for SAP error message /PM0/ABH_MESSAGE068 - Data types in adapter mapping class and proxy class are different ?

  The SAP error message /PM0/ABH_MESSAGE068 indicates that there is a mismatch between the data types defined in the adapter mapping class and those in the proxy class. This typically occurs during the integration of SAP systems, particularly when using SAP Process Integration (PI) or SAP Process Orchestration (PO).
  Cause:
  
  
  Data Type Mismatch: The data types defined in the source system (proxy class) do not match the expected data types in the target system (adapter mapping class). This can happen if:
  
  The data types have been changed in one of the systems but not in the other.
  There are discrepancies in the definitions of the data structures (e.g., length, type, or format).
  The mapping configuration is not updated after changes in the data structure.
  
  
  
  Versioning Issues: If there are different versions of the data types being used in the source and target systems, this can lead to incompatibility.
  
  
  Incorrect Mapping: The mapping configuration may not be correctly set up to handle the data types being passed.
  
  
  Solution:
  
  
  Check Data Types: 
  
  Review the data types in both the adapter mapping class and the proxy class. Ensure that they match in terms of type, length, and format.
  If there are discrepancies, update the data types in the relevant class to ensure they are consistent.
  
  
  
  Update Mapping: 
  
  If changes have been made to the data structure, ensure that the mapping configuration is updated accordingly. This may involve regenerating the mapping or manually adjusting the mapping logic.
  
  
  
  Regenerate Proxy: 
  
  If the proxy class has been modified, regenerate the proxy to ensure that it reflects the latest data structure.
  
  
  
  Test the Integration: 
  
  After making the necessary changes, test the integration to ensure that the error is resolved and that data is being processed correctly.
  
  
  
  Check for Version Compatibility: 
  
  Ensure that both systems are using compatible versions of the data types. If necessary, update the systems to align the versions.
  
  
  
  Related Information:
  
  SAP Documentation: Refer to the official SAP documentation for details on data types, mapping, and integration scenarios.
  SAP Community: Engage with the SAP Community forums for insights and solutions from other users who may have encountered similar issues.
  Debugging Tools: Utilize SAP's debugging tools to trace the data flow and identify where the mismatch occurs.
  
  By following these steps, you should be able to resolve the error message /PM0/ABH_MESSAGE068 and ensure that your SAP integration works smoothly.
