• What is the cause and solution for SAP error message LK015 - Within an IDOC, only transfer order data can exist ?

  The SAP error message LK015 indicates that within an IDoc (Intermediate Document), only transfer order data is allowed. This error typically arises when there is an attempt to process an IDoc that contains data not relevant to transfer orders, which violates the expected structure of the IDoc.
  Cause:
  The error can occur due to several reasons:
  
  Incorrect IDoc Structure: The IDoc being processed may contain segments or data that are not compatible with transfer orders. This could happen if the IDoc was incorrectly generated or if it includes data from a different context (e.g., sales orders, purchase orders).
  Mapping Issues: If there is a mapping issue in the middleware (like SAP PI/PO or other integration tools), it might lead to the inclusion of irrelevant data in the IDoc.
  Configuration Errors: There may be configuration issues in the IDoc type or message type that are not aligned with the expected data for transfer orders.
  
  Solution:
  To resolve the LK015 error, you can take the following steps:
  
  
  Check IDoc Structure: Review the structure of the IDoc being processed. Ensure that it only contains segments relevant to transfer orders. You can use transaction WE02 or WE19 to analyze the IDoc.
  
  
  Validate Data: Ensure that the data being sent in the IDoc is appropriate for transfer orders. Remove any irrelevant segments or fields that do not pertain to transfer orders.
  
  
  Review Mapping: If you are using middleware for IDoc processing, check the mapping configuration to ensure that it correctly translates the source data into the expected IDoc format for transfer orders.
  
  
  Consult Documentation: Refer to the SAP documentation for the specific IDoc type you are using to understand the required structure and fields for transfer orders.
  
  
  Test with Sample Data: Create a test IDoc with valid transfer order data to ensure that the processing works correctly. This can help isolate whether the issue is with the specific IDoc or a broader configuration issue.
  
  
  Check Custom Code: If there are any custom enhancements or user exits that manipulate IDoc data, review them to ensure they are not introducing invalid data.
  
  
  Related Information:
  
  IDoc Types: Familiarize yourself with the specific IDoc type used for transfer orders (e.g., MATMAS, TRFC, etc.) and their expected segments.
  Transaction Codes: Use transaction codes like WE02 (Display IDoc), WE19 (Test IDoc), and WE20 (Partner Profiles) for troubleshooting.
  SAP Notes: Check for any relevant SAP Notes that might address known issues or provide additional guidance on handling IDoc errors.
  
  By following these steps, you should be able to identify the root cause of the LK015 error and implement a solution to resolve it.
