Hi Donnette,
Sounds like a user is stuck in this window in a temp table. Have all users get out of GP and these tables should be empty when no users are in. If not, then delete them and try again.
SELECT * FROM DYNAMICS..ACTIVITY
SELECT * FROM DYNAMICS..SY00800
SELECT * FROM DYNAMICS..SY00801
SELECT * FROM TEMPDB..DEX_LOCK
SELECT * FROM TEMPDB..DEX_SESSION
DELETE DYNAMICS..ACTIVITY ---make sure all users are out before you run this.
DELETE DYNAMICS..SY00800
DELETE DYNAMICS..SY00801
DELETE TEMPDB..DEX_LOCK
DELETE TEMPDB..DEX_SESSION
Thanks,
Cheryl
