• What is the cause and solution for SAP error message WGDS_ENH116 - Select at least one working line containing a single material ?

  SAP Error Message:
  
  WGDS_ENH116: Select at least one working line containing a single material
  
  Cause:
  This error occurs in SAP when you try to perform an operation (usually in the context of production order processing, goods movement, or batch management) that requires selecting at least one line item (working line) which contains exactly one material. The system expects you to select a line with a single material to proceed, but either no line or multiple materials per line are selected.
  Common scenarios include:
  
  In the Goods Movement or Production Order Confirmation screens, the user tries to confirm or post goods without selecting a valid line item.
  The selected line contains multiple materials or is empty.
  The system enhancement or user exit expects a single material line to process, but the selection does not meet this criterion.
  
  
  Solution:
  
  
  Select a valid line:
  
  Ensure you select at least one line item that contains exactly one material. Check the list or table and select a single line with a single material.
  
  
  Check the selection criteria:
  
  If you are using filters or selection options, verify that they are set correctly to display lines with single materials.
  
  
  Review custom enhancements or user exits:
  
  If this error appears due to a custom enhancement (WGDS_ENH116 suggests an enhancement-related message), check the custom code or user exit that triggers this message. The logic might require adjustment to handle multiple materials or no selection cases properly.
  
  
  Check transaction and process:
  
  Confirm you are in the correct transaction and step where selecting a single material line is mandatory.
