  The SAP error message "EA785: Extension & and basic type & are not compatible" typically occurs in the context of IDoc processing, where there is a mismatch between the IDoc extension and the basic type defined in the system. This error indicates that the structure of the IDoc extension does not align with the structure of the basic type it is supposed to extend.
  Cause:
  
  Mismatch in Structure: The extension you are trying to use does not have the same structure as the basic type. This could be due to missing fields, additional fields, or different data types.
  Incorrect Configuration: The IDoc type or extension may not be correctly configured in the SAP system.
  Versioning Issues: If there are different versions of the IDoc types or extensions, this can lead to compatibility issues.
