• What is the cause and solution for SAP error message DMU180 - More than a standard alternative segment is maintained on node &1 ?

  The SAP error message DMU180, which states "More than a standard alternative segment is maintained on node &1," typically occurs in the context of the SAP Data Migration Workbench or during the use of the Data Migration Utility (DMU). This error indicates that there are multiple standard alternative segments defined for a specific node in the data model, which is not allowed.
