  SAP Error Message:
  
  WER274 &1 is not compatible with &2
  
  Cause:
  This error typically occurs when there is an incompatibility between two objects or components in SAP. The placeholders &1 and &2 represent the names or types of the objects that are being checked for compatibility. For example, this can happen during configuration, data transfer, or integration scenarios where one object (like a data type, structure, or function module) is expected to be compatible with another, but they are not.
  Common scenarios include:  
  
  Mismatched data types or structures in interfaces or IDocs.  
  Incompatible versions of software components or add-ons.  
  Incorrect assignment of objects in customizing or development.  
  Using incompatible business objects or classes in workflows or BAPIs.

  Ensure that the data types or interfaces match in terms of fields, data length, and types.
  
  
  
  Adjust or Correct:  
  
  Modify the object definitions to make them compatible if possible.  
  Use appropriate conversion or mapping if direct compatibility is not possible.  
  Update or upgrade components to compatible versions if version mismatch is the cause.
