Limit for maximum number of inspections reached for user &1

What causes this issue?

There can be no more than 999 global inspections for each user. This
limit would be exceeded for the user &V1& by the current inspection.

System Response

No more inspections can be created for the user &V1&.

How to fix this error?

To create new inspections in the short term, delete some older
inspections and run the report RS_CI_DELETE.
In the long term, consider the following ways of reducing the number of
different inspections:
Make use of the option of creating up to 999 different versions for a
single inspection.
Set the "Delete" date for inspections a few days after the "Create"
date. The default "Delete" date is 50 days after the "Create" date.
Inspections with regular scheduling should not be executed too often.
Use a few inspections to examine larger sets of objects rather than
creating separate inspections for many different objects.
