Status: Awaiting fix
Reference: CE00043439
Issue
(CA306000) Warning message on left panel in Process Bank transaction Screen won’t stay all the time. The warning message will disappear when select on some other lines
Workaround
Not needed. Transaction is not marked as Matched so will not be processed when Process action is taken. User will have to get back to this transaction anyway to complete the matching and will see warning then.
