  Error Message
  WY093: Supplier characteristic value & exists twice
  
  Cause
  This error occurs when you try to maintain or assign supplier characteristics in SAP, and the system detects that the same characteristic value for a supplier is entered more than once. In other words, there is a duplicate entry of a characteristic value for the same supplier in the system.
  Supplier characteristics are used in SAP to classify suppliers based on certain attributes (e.g., region, product group, quality rating). Each characteristic value should be unique per supplier to avoid ambiguity.
  
  When does it occur?
  
  During the creation or change of supplier master data.
  When maintaining supplier characteristics in transaction MK02 (Change Vendor) or MK01 (Create Vendor).
  When uploading supplier characteristics via batch input or data migration tools.
  When assigning characteristics in classification views.
  
  
  Solution
  
  
  Check for Duplicate Entries:
  
  Go to the supplier master data and check the classification tab.
  Look for duplicate characteristic values assigned to the same supplier.
  Remove or correct the duplicate entries.
  
  
  
  Use Transaction Codes:
  
  Use CL20N (Change Object Characteristics) or CL30N (Display Object Characteristics) to view and edit the classification data for the supplier.
  Identify and delete duplicate characteristic values.
  
  
  
  Data Consistency Check:
  
  Run consistency checks or reports to find duplicates in supplier characteristics.
  If duplicates are found in the database, clean them up.
  
  
  
  During Data Upload:
  
  If the error occurs during data migration or batch upload, check the source data for duplicates.
  Correct the source file before re-uploading.
  
  
  
  Preventive Measures:
  
  Implement validation checks in custom programs or interfaces to prevent duplicate characteristic values from being entered.
  Train users on correct data entry procedures.
