MN551 - Details

• The SAP error message MN551 indicates that there is a mismatch between the reference magnitudes in the document condition and the condition record. This typically occurs in the context of pricing or condition records in SAP, particularly when dealing with sales documents, purchase orders, or other transactional documents that involve pricing conditions.
  
  Cause:
  
  
  Mismatch in Reference Magnitudes: The error arises when the reference magnitude (e.g., quantity, weight, volume) used in the document does not match the reference magnitude defined in the condition record. For example, if the condition record is set up for a specific unit of measure (UoM) and the document is using a different UoM, this error will occur.
  
  
  Incorrect Condition Records: The condition records may not be set up correctly for the specific scenario or may not cover the required reference magnitude.
  
  
  Data Entry Errors: There may be manual data entry errors in the document or condition records that lead to
