Inconsistent user-defined check result data change in item &1

What causes this issue?

An active version exists for the Business Add-In
/SCWM/EX_DLV_AVAIL_CHECK (processing input and output data of the
availability check). The change of the requirement item data or the
configuration data in method AFTER_AVAILABILITY_CHECK is not consistent
and could cause runtime errors during the availability check or errors
when processing the check results.

System Response

The change of the requirement item data and configuration data was reset
. The check was carried out using the original data before the BAdI
method was executed.

How to fix this error?

Check the result of your active implementation of BAdI method
/SCWM/IF_EX_DLV_AVAIL_CHECK->AFTER_AVAILABILITY_CHECK for the following
points and, if necessary, correct the implementation:
A corresponding entry in the table of configuration data must exist for
each of the item IDs. This means that no entry in the check results must
be deleted without being replaced and no item ID must be changed.
There must be no other entries in the table of configuration data
without corresponding entries in the table of requirement item data.
