Legal Hold: Assign a BOR object to ILM object &1 (if available)

What causes this issue?

The ILM standard stipulates that the specifications for the BOR object
and its key needed by legal holds must exist so that customers can
protect locked BOR object instances from data destruction.
In the case of your ILM object &V1&, no BOR object with a related key
definition has been entered in transaction IRM_CUST.

System Response

This message is only a warning.

How to fix this error?

Check whether a BOR object logically belongs to the archiving and ILM
object.
