• What is the cause and solution for SAP error message COM_DML_ENGINE050 - Header data was changed ?

  The SAP error message COM_DML_ENGINE050 with the description "Header data was changed" typically occurs in the context of document processing, particularly when dealing with documents that have header and item data, such as sales orders, purchase orders, or other transactional documents.
  Cause:
  This error usually arises when there is a discrepancy between the header data and the item data of a document. Common causes include:
  
  Concurrent Updates: If multiple users or processes are trying to update the same document simultaneously, one user's changes may overwrite another's, leading to inconsistencies.
  Data Validation: If the header data is modified after the item data has been processed, the system may detect that the header has changed and throw this error to prevent inconsistencies.
  User Exits or BAdIs: Custom code or enhancements that modify header data during processing can lead to this error if they are not properly synchronized with item data updates.
  Workflow Issues: If the document is part of a workflow and the header is updated outside of the expected process flow, it can trigger this error.
  
  Solution:
  To resolve the COM_DML_ENGINE050 error, consider the following steps:
  
  Check for Concurrent Updates: Ensure that no other users or processes are trying to update the same document at the same time. If possible, implement locking mechanisms to prevent concurrent updates.
  Review Custom Code: If there are any user exits, BAdIs, or custom enhancements that modify header data, review them to ensure they are not causing conflicts with item data.
  Revalidate Data: Before saving or processing the document, revalidate the header and item data to ensure they are consistent. This may involve re-fetching the latest header data before processing items.
  Debugging: If the issue persists, consider debugging the process to identify where the header data is being changed unexpectedly. Use transaction codes like SE80 or SE37 to analyze the relevant function modules or methods.
  Consult Documentation: Check SAP Notes and documentation for any known issues or patches related to this error message. SAP may have provided updates or fixes for specific scenarios.
