  SAP Error Message:
  WGDS_ENH_EMPTIES004: Assignment of article &1 to GTIN &2 is already available
  
  Cause:
  This error occurs when you try to assign a GTIN (Global Trade Item Number) to an article (material) in SAP, but the system detects that this assignment already exists. In other words, the article &1 is already linked to the GTIN &2 in the system, so attempting to create the same assignment again leads to this error.
  This typically happens during:
  
  Creation or update of article master data with GTIN assignments.
  Data upload or migration where duplicate GTIN-article assignments are attempted.
  Enhancements or custom validations related to GTIN assignments in SAP WM, EWM, or SAP S/4HANA Retail.
  
  
  Solution:
  
  
  Check Existing Assignments:
  
  Verify if the GTIN &2 is already assigned to the article &1.
  Use transaction codes or reports to check GTIN assignments, e.g., MM03 (Display Material), and check the GTIN or barcode data.
  In SAP Retail or EWM, check the relevant tables or master data views for GTIN assignments.
  
  
  
  Avoid Duplicate Assignments:
  
  If the assignment already exists, do not attempt to create it again.
  If you are performing a data upload or migration, cleanse the data to remove duplicates before uploading.
  
  
  
  Correct the Data Upload or Interface:
  
  If the error occurs during an interface or batch job, adjust the logic to skip or update existing assignments rather than inserting duplicates.
  
  
  
  Check Custom Enhancements:
  
  If the error is raised by a custom enhancement (as the message prefix WGDS_ENH suggests), review the enhancement code or user-exit to understand why it is triggered.
  Modify the enhancement logic to handle existing assignments gracefully.
  
  
  
  
  Related Information:
  
  GTIN (Global Trade Item Number): A unique identifier for trade items, used globally for product identification.
  SAP Modules Involved: Retail (IS-Retail), Extended Warehouse Management (EWM), Materials Management (MM).
  Tables to Check:
  
  MARA (General Material Data)
  MARC (Plant Data for Material)
  EAN* tables (e.g., EAN13 or EAN_DATA) for GTIN/barcode assignments.
  
  
  Transactions:
  
  MM03 - Display Material
  MM02 - Change Material (to check or update GTIN)
  Custom reports or tools for GTIN management in Retail or EWM.
  
  
  
  
  Summary:
  The error WGDS_ENH_EMPTIES004 indicates a duplicate GTIN-to-article assignment attempt. To resolve it, verify existing assignments, avoid duplicates, cleanse data during uploads, and review any custom enhancements that enforce GTIN assignment rules.
