RE: GP 2013 NSF function does not go to Bank reconciliation
I will add to the glee chorus of folks who tried this and GP worked as designed. I too was rewarded with a WDL transaction in my Bank Reconciliation module, corresponding to the NSF transaction processed in Receivables Posted Transaction Maintenance.
Two possible issues come to mind, which might explain the behavior you're encountering. First, security. If the user does not have posting privileges for these types of transactions, the process would not complete.
Additionally, if there were something wrong with your registration keys, or Bank Reconciliation was not checked in the Registration window, you would have problems with this feature.
