• What is the cause and solution for SAP error message WSTI_DOC005 - You have already entered material &1. ?

  SAP Error Message:
  
  WSTI_DOC005: You have already entered material &1.
  
  Cause:
  This error occurs in SAP when you try to enter a material that has already been entered in the same document or transaction. Typically, this happens in processes like Goods Receipt, Goods Issue, or other inventory-related transactions where the system expects unique material entries per line or item. The system detects a duplicate material entry and prevents it to avoid inconsistencies or redundant data.
  
  When does it occur?
  
  During creation or editing of a document (e.g., delivery, goods movement, production order confirmation).
  When the same material number is entered more than once in the item overview or detail screen.
  In transactions or custom programs where material entries must be unique per document.
  
  
  Solution:
  
  
  Check for Duplicate Entries:
  
  Review the document or transaction screen to identify if the material number has been entered more than once.
  Remove or consolidate duplicate material entries if they are not required.
  
  
  
  If Multiple Entries Are Required:
  
  Some business processes allow multiple entries of the same material but with different batch numbers, storage locations, or other distinguishing fields.
  Ensure that these differentiating fields are correctly filled to allow multiple entries.
  If the system still throws the error, check if the configuration or validation logic restricts duplicates.
  
  
  
  Check Custom Validations/User Exits:
  
  Sometimes, custom code or user exits/enhancements enforce uniqueness of material entries.
  Review any custom logic that might be causing this error and adjust if necessary.
  
  
  
  SAP Notes and Support:
  
  Search SAP Notes for WSTI_DOC005 for any known issues or patches.
  If the error occurs unexpectedly, consider raising a support ticket with SAP.

  Transaction Codes: MB1A, MB1B, MIGO, VL02N, CO11N (depending on the process).
  Tables: MKPF (Material Document Header), MSEG (Material Document Segment) for material document entries.
  Configuration: Check movement types and document types if they have restrictions on duplicate materials.
  User Exits/BADIs: Look for enhancements in the material document processing that might enforce uniqueness.
  
  
  Summary:
  
  Cause: Duplicate material entry detected in the same document.
  Solution: Remove duplicates or differentiate entries properly; check custom validations.
  Check: Document lines, batch/storage location fields, custom code, SAP Notes.
