Pool & still exists in the database

What causes this issue?

When trying to delete a matchcode object, the pool created for the
matchcode object was found to exist still in the database.

System Response

The matchcode definition cannot be deleted from the ABAP/4 Dictionary
because data might be lost during the delete operation. The delete
operation is rejected, no changes are made.

How to fix this error?

The pool belonging to the matchcode object must be explicitly deleted
before the matchcode definition can be removed from the ABAP/4
Dictionary. To delete the matchcode pool, call the function
<LS>Database utility</> from the <LS>Utility</> menu of the matchcode
object maintenance screen. After a save prompt, the matchcode pool is
deleted from the database. The data built for this matchcode are lost
(unless an older database version can be imported).
