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.

  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.
  
  Configuration Issues: There may be configuration issues with the NRIV tables that need to be addressed before the migration can continue.
  
  
  Solution:
  
  Check Active Processes: Identify any active processes that might be using the NRIV tables. You can use transaction codes like SM66 (Global Work Process Overview)
