How to fix this error?

In addition to table NRIV, at least one more table is used for number
assignment:
NRIV_LOKAL - Local NRIV for multi-processor machines;
NRIV_RESTE - Not assigned internal numbers (if NRIV is split up)
NRIVSHADOW - Local NRIV for multi-processor machines
This requires a project-specific solution.
For background information, see SAP Note 1398444. The problem to be
expected is described in SAP Note 1019692.
To be able to proceed with your work on the mapping, you can use the
transaction CNV_SETYELLOW. In parallel, however, you need to find a
project-specific solution for these three tables.
If you encounter any problems while doing so, contact SLO development.

This error indicates that there are other NRIV (Number Range Interval) tables currently in use, which can lead to conflicts or inconsistencies during the migration process.
  Cause:
  
  Concurrent Usage: The error often arises when there are active processes or transactions that are using the same number range intervals that the migration process is trying to access or modify.
  Locked Number Ranges: If the number ranges are locked or being used by other transactions, the migration process cannot proceed.

  Release Locks: If you find that there are locks on the NRIV tables, you may need to wait for those processes to complete or manually release the locks if appropriate.
  Review Number Range Configuration: Ensure that the number ranges are correctly configured and not overlapping with other processes. You can check this in transaction SNRO (Number Range Objects).

  Consult SAP Notes: Check for any relevant SAP Notes that may provide additional guidance or patches related to this error. You can search for notes using the SAP Support Launchpad.
