• What is the cause and solution for SAP error message UGMD568 - Data records were lost during the conversion of table &1 ?

  The SAP error message UGMD568 indicates that data records were lost during the conversion of a specific table (denoted by &1). This typically occurs during data migration or conversion processes, such as when upgrading to a new version of SAP or when performing data transformations.
