• What is the cause and solution for SAP error message DT336 - Technical layout of proxy object & and & do not match ?

  The SAP error message DT336, which states "Technical layout of proxy object & and & do not match," typically occurs in the context of SAP Process Integration (PI) or SAP Process Orchestration (PO) when there is a mismatch between the technical structures of the proxy objects involved in a communication scenario. This can happen when the data structures defined in the proxy interfaces do not align with the expected structures in the receiving or sending system.
  Causes:
  
  Changes in Data Structures: If there have been changes to the data structures (e.g., fields added, removed, or modified) in the proxy interface after the proxy was generated, this can lead to mismatches.
  Versioning Issues: If different versions of the proxy objects are being used, it can cause discrepancies in the expected data layout.
  Incorrect Mapping: If the mapping between the source and target structures is not correctly defined, it can lead to this error.
  Transport Issues: If the proxy objects were transported between systems (e.g., from development to production) and the structures were not synchronized, this error may occur.
  
  Solutions:
  
  
  Regenerate Proxy Objects: If there have been changes to the data structures, regenerate the proxy objects in the relevant systems to ensure they are in sync.
  
  In the SAP system, navigate to the relevant transaction (e.g., SPROXY) and regenerate the proxy.
  
  
  
  Check Mapping: Review the mapping configuration in the Integration Directory or the relevant mapping tool to ensure that the source and target structures are correctly aligned.
  
  
  Version Consistency: Ensure that the same version of the proxy objects is being used across all systems involved in the communication. If necessary, update the proxy in the consuming system to match the latest version.
  
  
  Transport Consistency: If the proxy objects were transported, ensure that all related objects (like data types, message types, etc.) were also transported and are consistent across systems.
  
  
  Debugging: Use debugging tools to trace the execution and identify where the mismatch occurs. This can help pinpoint the exact cause of the error.
