DGHU118 - Details

• The SAP error message DGHU118 indicates that a replacement material is already assigned to a specific specification. This typically occurs in the context of material management and product specifications within SAP, particularly when dealing with material master records and their relationships.
  
  Cause:
  
  Existing Assignment: The replacement material you are trying to assign is already linked to another specification. This can happen if the material has been previously defined as a replacement for a different material.
  Data Integrity Rules: SAP enforces data integrity rules to prevent multiple assignments of the same replacement material to different specifications, which can lead to confusion and inconsistencies in data.
  
  
  Solution:
  
  
  Check Existing Assignments: 
  
  Navigate to the relevant transaction (e.g., MM03 for material master) and check the specifications assigned to the replacement material. 
  Identify if the material is already linked to another specification and determine if that assignment is still valid.
  
  
  
  Remove or Change Assignment:
