VF376 - Details

• The SAP error message VF376 indicates that the numbering routine has returned a prefix "TMP," which is reserved for system use. This typically occurs in the context of billing documents or invoice processing in SAP.
  
  Cause:
  The error is caused by the system attempting to generate a document number using a prefix that is not allowed for user-defined document types. The prefix "TMP" is reserved for temporary documents or system-generated documents, and it cannot be used for standard billing documents or invoices.
  
  Solution:
  To resolve this issue, you can take the following steps:
  
  
  Check Number Range Configuration:
  
  Go to transaction code SNRO (Number Range Objects).
  Look for the number range object related to billing documents (e.g., FBNR for billing documents).
  Ensure that the number range is correctly defined and that the prefix used is not "TMP."
  
  
  
  Adjust Numbering Routine:
  
  If you have custom logic in your numbering routine, review it to ensure it does not return the "TMP" prefix.
