• What is the cause and solution for SAP error message E1150 - Combination of basic type and extension is possible ?

  The SAP error message E1150, which states "Combination of basic type and extension is possible," typically occurs in the context of IDoc processing. This error indicates that there is a mismatch or an issue with the IDoc structure being used in relation to the basic type and its extension.
  Cause:
  
  
  IDoc Structure Mismatch: The error often arises when the IDoc being processed does not match the expected structure defined by the basic type and its extension. This can happen if:
  
  The IDoc type being sent does not have the correct segments or fields as defined in the basic type.
  The extension of the IDoc is not properly defined or is missing required segments.
  
  
  
  Incorrect Mapping: If you are using a middleware or an interface to map data to the IDoc, incorrect mapping can lead to this error.
  
  
  Versioning Issues: If there are changes in the IDoc structure (like adding or removing fields) and the system is still using an older version of the IDoc, this can lead to compatibility issues.
  
  
  Solution:
  
  
  Check IDoc Definition: Verify that the IDoc definition in the SAP system matches the structure of the IDoc being sent. Ensure that all required segments and fields are present.
  
  
  Review Extensions: If you are using an extension of a basic type, ensure that the extension is correctly defined and that it includes all necessary segments.
  
  
  Mapping Validation: If you are using middleware (like SAP PI/PO or other integration tools), check the mapping configuration to ensure that it aligns with the IDoc structure.
  
  
  Testing with Sample Data: Test the IDoc with sample data that adheres to the expected structure to see if the error persists. This can help isolate whether the issue is with the data being sent.
  
  
  Consult Documentation: Refer to SAP documentation for the specific IDoc type you are working with to ensure compliance with the expected structure.
  
  
  Debugging: If you have access to debugging tools, you can trace the IDoc processing to identify where the mismatch occurs.
  
  
  Related Information:
  
  IDoc Types: Understand the basic types and extensions in SAP IDocs. Each IDoc type has a defined structure that includes segments and fields.
  Transaction Codes: Use transaction codes like WE30 (IDoc Types), WE31 (IDoc Segments), and WE20 (Partner Profiles) to manage and review IDoc configurations.
  SAP Notes: Check SAP Notes for any known issues or updates related to the specific IDoc type you are working with.
  
  By following these steps, you should be able to identify the cause of the E1150 error and implement a solution to resolve it.
