• What is the cause and solution for SAP error message GK279 - Item &1 is already assigned to item hierarchy &2 ?

  The SAP error message GK279 indicates that a specific item (identified by &1) is already assigned to a particular item hierarchy (identified by &2). This error typically occurs in the context of managing item hierarchies in SAP, particularly in modules related to materials management or product hierarchy management.
  Cause:
  
  Duplicate Assignment: The item you are trying to assign to the hierarchy is already linked to another hierarchy or the same hierarchy.

  Solution:
  
  Check Current Assignments: Verify the current assignments of the item in question. You can do this by navigating to the item hierarchy management screen and checking where the item is currently assigned.
  Remove Existing Assignment: If the item needs to be moved to a different hierarchy, you may need to first remove it from its current hierarchy before assigning it to the new one.
  Use Different Item: If the item must remain in its current hierarchy, consider using a different item for the new assignment.
  Consult Documentation: Review SAP documentation or help files related to item hierarchies for specific instructions on managing assignments.
  Check User Authorizations: Ensure that you have the necessary permissions to make changes to item hierarchies.
