/PLMB/OSET004 - Details

• The SAP error message /PLMB/OSET004 Object &1 is already assigned to object set &2 typically occurs in the context of SAP's Product Lifecycle Management (PLM) module, specifically when dealing with object sets. This error indicates that the object you are trying to assign (represented by &1) is already associated with another object set (represented by &2).

  Solution:
  
  Check Current Assignments: Before assigning the object to a new object set, check which object set it is currently assigned to. You can do this by navigating to the object set management area in SAP and reviewing the assignments.
