• What is the cause and solution for SAP error message WG036 - Empty document item table transferred ?

  SAP Error Message:
  
  WG036 - Empty document item table transferred
  
  Cause:
  This error occurs when a function module or program in SAP expects a document with item data (line items), but the item table passed to it is empty. In other words, the header data might be present, but no corresponding item data has been transferred or filled in the internal tables during the document creation or processing.
  Common scenarios include:
  
  Posting or creating a document (e.g., delivery, billing, goods movement) where the item data is missing.
  Calling BAPIs or function modules that require item data, but the item table parameter is empty.
  Data transfer or interface programs that do not populate the item table correctly.
  
  
  Solution:
  
  
  Check the Data Population Logic:
  
  Ensure that the program or interface filling the document data correctly populates the item table.
  Verify that the item data is not accidentally filtered out or lost before the function call.
  
  
  
  Debug the Program:
  
  Use the debugger to check the contents of the item table just before the function module or BAPI call.
  Confirm that the item table is not empty and contains all required fields.
  
  
  
  Review the Interface or Input Data:
  
  If the document is created via an interface (e.g., IDoc, BAPI), check the source data to ensure item details are included.
  Validate the mapping and data extraction logic.
  
  
  
  Check Mandatory Fields:
  
  Sometimes, missing mandatory fields in item data can cause the system to ignore or drop items.
  Make sure all required fields for items are filled.
  
  
  
  SAP Notes and Documentation:
  
  Search for SAP Notes related to the specific function module or BAPI you are using.
  Sometimes, patches or corrections are available for known issues.

  Summary:
  WG036 - Empty document item table transferred means the system expected item data for a document but received none. The fix involves ensuring that the item table is properly filled before the document processing call. Debugging and verifying the data flow from the source to the function call is key to resolving this error.
