  Error Message
  WPM_PROMO_2002: Material &1 already exist
  
  Cause
  This error occurs when you try to create or assign a material in a promotion or campaign in SAP (typically within SAP Promotion Management or SAP Trade Promotion Management) but the material you are trying to add already exists in the current promotion or campaign context.
  In other words, the system detects a duplicate entry of the same material in the promotion, which is not allowed.
  
  When does it typically occur?
  
  While creating or editing a promotion or campaign.
  When adding materials to a promotion or campaign.
  During data upload or mass maintenance of promotion materials.
  When trying to assign a material that is already assigned to the same promotion.
  
  
  Solution
  
  
  Check for duplicates:
  
  Review the list of materials already assigned to the promotion or campaign.
  Verify if the material you are trying to add is already present.
  
  
  
  Remove or avoid duplicates:
  
  If the material is already assigned, do not add it again.
  If you need to update the material details, edit the existing entry instead of creating a new one.
  
  
  
  Data upload or interface checks:
  
  If the error occurs during data upload (e.g., via BAPI, IDoc, or batch input), check the source data for duplicates.
  Clean the data before upload to avoid duplicate entries.
  
  
  
  Check promotion validity:
  
  Sometimes, the material might be assigned in overlapping promotions or conflicting validity periods. Ensure that the material assignment is unique per promotion and validity period.
  
  
  
  Technical checks:
  
  If the error persists and you believe it is incorrect, check for custom enhancements or user exits that might be causing the duplicate check to fail.
  Debug the function module or program that triggers the error message to understand the logic.
