• What is the cause and solution for SAP error message WER364 - Item cannot by initial ?

  SAP Error Message:
  
  WER364 - Item cannot be initial
  
  Cause:
  This error occurs when an item field that is not allowed to be initial (empty or zero) is found to be initial during processing. In SAP, certain fields, especially key fields or mandatory fields in documents or master data, must have a valid value and cannot be left blank or zero. The system checks these fields during data entry or processing and throws this error if the field is initial.
  For example, in sales documents, purchase orders, or inventory postings, line items must have certain mandatory fields filled (like material number, item number, quantity, etc.). If any of these fields are left initial, the system will raise this error.
  
  Typical Scenarios:
  
  Creating or changing documents where item data is incomplete.
  Uploading or interfacing data where mandatory item fields are missing.
  Custom developments or user exits where item fields are not properly populated.
  Data migration or batch input sessions with incomplete item data.
  
  
  Solution:
  
  
  Check the Item Data:
  
  Identify which item field is initial and ensure it is populated with a valid value. This usually involves:
  
  Reviewing the document or transaction data.
  Ensuring all mandatory fields for the item are filled.
  
  
  
  Correct the Input Data:
  
  If the error occurs during data upload or batch input, verify the source data and correct missing fields.
  
  
  Debugging (if needed):
  
  If the error is not obvious, debugging the transaction or program where the error occurs can help identify which field is initial and causing the problem.
  
  
  Check Custom Code/User Exits:
  
  If custom enhancements or user exits are involved, verify that they do not clear mandatory item fields or leave them initial.
  
  
  SAP Notes and Documentation:
  
  Search for SAP Notes related to message WER364 for specific module or transaction context, as the exact field and cause can vary.
  
  
  
  Related Information:
  
  Message Class: WER (related to sales and distribution or document processing)

  SAP Modules: SD (Sales and Distribution), MM (Materials Management), WM (Warehouse Management), or others depending on where the error occurs.
  Debugging Tools: Use transaction SE91 to look up message WER364, and SE38/SE80 to check programs or user exits.

  Summary:
  WER364 - Item cannot be initial means a mandatory item field is empty or zero when it must have a value. The solution is to ensure all required item fields are properly filled before saving or processing the document.
