The SAP error message CNV_00001519 indicates that a specific table (denoted as &1) was not added manually during a data migration or conversion process, and instead of adding it, the system suggests setting the 'Exclude' flag for that table. This message is typically encountered in the context of SAP data migration projects, particularly when using the SAP S/4HANA Migration Cockpit or other data migration tools.
Cause: Automatic Table Handling: The error arises when the system detects that a table was not manually included in the migration process. This could be due to the table being automatically managed by the system or not being relevant for the migration.
Configuration Issues: There may be configuration settings that dictate which tables should be included or excluded during the migration process. Data Model Changes: The table in question may not be relevant in the new data model or may have been deprecated in the target system.
