  SAP Error Message WR127: "You can only enter material once"
  
  Cause:
  The error message WR127 occurs when you try to enter the same material more than once in a context where the system expects each material to be entered only once. This typically happens in transactions or processes where duplicate entries of the same material are not allowed, such as:
  
  Creating or editing a goods receipt or goods issue document.
  Entering materials in a reservation or production order.
  Entering materials in a delivery or billing document line item.
  
  The system enforces uniqueness to avoid inconsistencies or duplication in inventory or document processing.
  
  Solution:
  To resolve the WR127 error, you should:
  
  
  Check the material entries:
  
  Review the list of materials you have entered and ensure that each material appears only once.
  
  
  Consolidate quantities:
  
  If you need to enter multiple quantities of the same material, enter it once and specify the total quantity rather than entering the material multiple times.
  
  
  Remove duplicates:
  
  Delete any duplicate material lines from the document or transaction.
  
  
  Use item categories or split lines if needed:
  
  If you need to differentiate between different batches, storage locations, or other attributes, use the appropriate fields or item categories instead of entering the same material multiple times.
