CRQ is abbreviated terminology for 'CLOSE REQUESTED'. This is a CICS FILE CONTROL status that CA DADS Plus is merely reporting to you.
If you issue a CEMT on the same file you will see 'CLOSE REQUESTED' which indicates that there has been a request to close the file but for some reason the file is locked.
CICS is going to deny any further requests to access this file due to the pending CLOSE. This is not a CA DADS Plus problem and determining the cause of the lock on the file is outside the current scope of CA DADS Plus.
Determine what task has a lock on the file in question and resolve it.
