• What is the cause and solution for SAP error message WTY091 - Relation type &1 is not allowed between versions ?

  SAP Error Message:
  WTY091 - Relation type &1 is not allowed between versions
  
  
  Cause:
  This error occurs when you try to create or maintain a relationship (dependency) between two objects (such as BOMs, documents, or engineering change management objects) where the relation type specified is not permitted between different versions of these objects.
  In SAP Engineering Change Management (ECM) or Document Management System (DMS), certain relation types are restricted to be used only between objects of the same version or only between objects of different versions. If you attempt to assign a relation type that is not allowed between versions, the system throws this error.
  
  Explanation:
  
  Relation types define how objects are linked (e.g., "is replaced by", "is part of", "is referenced by").
  Some relation types are only valid between objects of the same version.
  Others may be valid only between objects of different versions.
  If you try to assign a relation type that violates these rules, SAP raises
