My Assistant using contain condition

SUGGESTED

I am creating an condition in My Assistant that pulls all the GL and CM transactions based on a certain prefix. Here is what I have so far and it works. When I try to add Prefix AB = 'XXX-123', it brings me back no data when I know there is. Any suggestions.
("GLT_CURRENT__TRANSACTION"."Date_Stamp" = CURDATE()  and "GLT_CURRENT__TRANSACTION"."Application_of_Origin" = 'GL') or
("GLT_CURRENT__TRANSACTION"."Date_Stamp" = CURDATE()  and "GLT_CURRENT__TRANSACTION"."Application_of_Origin" = 'CM')
