  The SAP error message CNV20200139 indicates that certain domains were excluded from a conversion process, typically during a data migration or system conversion project. This message is part of the SAP S/4HANA migration or data conversion process, particularly when using the SAP S/4HANA Migration Cockpit or other related tools.
