ICU1042 INVALID CHANGE REQUESTED

Explanation
A control statement requests a change to an entry
in the cryptographic key data set (CKDS); however, the change conflicts
with the existing entry. For a REASGN control statement, if the new
label already exists on the CKDS, it must contain the same type of
key-encrypting key as the existing label entry. For a LOCAL, REMOTE,
or CROSS control statement, the updated or deleted entry must have
the same type of key-encrypting key as the old CKDS entry. That is,
to update or delete a local key, use a LOCAL control statement; to
update or delete a remote key, use a REMOTE control statement; and
to update or delete cross keys, use a CROSS control statement. The
control statement containing the error precedes this message.

System action
Processing ends for this control statement. Processing
continues for any other control statements.

Programmer response
Correct the control statement in error.
Rerun the key generator utility program, specifying the CHGK function
on the EXEC statement and providing the corrected control statement.
