I don’t know ACCOUNT TRANSACTION DETAILS
very well, bt I imagine the problem is that the waiter/current user is not something that is accessable from that report.
Take a read of @QMcKay’s answer to one of my questions a while ago. You can use the result of one report to feed in to another report. So you might do something like retrieve a list of ticket numbers per waiter from REPORT PAYMENT DETAILS
and then feed these numbers in to the ACCOUNT TRANSACTION DETAILS
report.
Q explains it better than me, so go and have a read, it should give you some hints…
