  SAP Error Message: WGDS_PROCESS128
  Text:
  
  In Segment PPRODUNITS, key &1 EAN &2 date &3 is duplicate
  
  Cause:
  This error occurs during the processing of data in the PPRODUNITS segment (which typically relates to product units or packaging units in SAP) when the system detects duplicate entries for the same key combination. Specifically:
  
  The key (usually a product or material number)  
  The EAN (European Article Number or barcode)  
  The date (validity or effective date)
  
  are found more than once in the data being processed or uploaded.
  Duplicate entries violate the uniqueness constraint expected by SAP for this segment, causing the system to throw this error.
  
  When does it occur?
  
  During data upload or data transfer processes (e.g., using IDocs, BAPIs, or batch input sessions) involving product unit data.  
  When maintaining or updating packaging or unit of measure data for materials.  
  When integrating data from external systems or during master data replication.
  
  
  Solution:
  
  
  Check the source data:  
  
  Verify the data file or source system for duplicate records with the same key, EAN, and date.  
  Remove or correct duplicate entries before uploading.
  
  
  
  Data cleansing:  
  
  Ensure that each combination of product key, EAN, and date is unique.  
  If multiple entries are needed, check if the date ranges or validity periods overlap and adjust accordingly.
  
  
  
  SAP data validation:  
  
  Use transaction codes like MM02 (Change Material) or relevant master data transactions to check existing entries for duplicates.  
  Use reports or queries to identify duplicates in the system.
  
  
  
  Adjust upload logic:  
  
  If the data is uploaded via custom programs or interfaces, add logic to check for duplicates before posting.
  
  
  
  Consult SAP Notes:
