You want to get the structure information for table &V1&. In accordance

routine.

The SAP error message CNV_10020582 indicates that there is no exit routine available for determining structure information in the context of a data conversion or migration process. This error typically arises during the execution of a data migration project, particularly when using SAP's Conversion Tools or the SAP S/4HANA Migration Cockpit.
Cause: Missing Custom Logic: The error often occurs when a custom exit routine that is supposed to provide structure information is not implemented or is missing in the system.
Configuration Issues: There may be configuration issues in the migration project that prevent the system from finding the necessary exit routines. Incorrect Data Mapping: If the data mapping is not correctly defined, the system may not be able to determine how to handle the data structures. Version Compatibility: The error may also arise if there are compatibility issues between the version of the migration tool being used and the SAP system.
Solution: Check for Exit Routines: Verify
