• What is the cause and solution for SAP error message 0K112 - Item fields cannot be added to a header line ?

  The SAP error message 0K112: Item fields cannot be added to a header line typically occurs when there is an attempt to add item-level fields to a header-level structure in a transaction or report where such an operation is not allowed. This error is common in scenarios involving document processing, such as sales orders, purchase orders, or other transactional data where there is a clear distinction between header and item data.
  Cause:
  
  Data Structure Misalignment: The error usually arises when the program or transaction is trying to assign item-specific fields (like quantity, price, etc.) to a header structure (which typically contains general information like document number, date, etc.).
  Incorrect Configuration: It may also occur due to incorrect configuration in the data model or in the way the data is being processed in the ABAP code.
  Custom Development Issues: If there are custom developments or enhancements in the system, they might be incorrectly handling the data structures.
  
  Solution:
  
  Check Data Assignment: Review the code or configuration where the error occurs. Ensure that item fields are being assigned to the correct item structure and not to the header structure.
  Debugging: If you have access to the ABAP debugger, you can set breakpoints to see where the error is triggered and inspect the data being processed.
  Review Custom Code: If there are custom programs or enhancements, check for any logic that might be incorrectly trying to assign item fields to a header.
  Consult Documentation: Refer to SAP documentation or notes related to the specific transaction or module you are working with to ensure compliance with expected data structures.
  SAP Notes: Check the SAP Support Portal for any relevant notes or patches that might address this issue.
