  The SAP error message VMP_MSG098 ("Manufacturing Structure already exists") typically occurs in the context of SAP's Variant Configuration or Production Planning modules. This error indicates that there is an attempt to create or modify a manufacturing structure (such as a Bill of Materials or routing) that already exists in the system.
  Cause:
  
  Duplicate Entry: The most common cause is that the manufacturing structure you are trying to create or modify already exists in the system with the same key or identifier.
