• What is the cause and solution for SAP error message UGMD311 - &1 is already used in hierarchies; assignment not possible ?

  The SAP error message UGMD311 indicates that a specific characteristic or node (denoted by &1) is already being used in one or more hierarchies, which prevents it from being assigned to another hierarchy or structure.
