This may be a bit unusual, but here's what I'm trying to do.
I have a transaction-based inventory tracker to keep track of how many electrodes are on hand at any point. Some of these Electrodes are part of a Purchase Order (PO) so we added the option to tag a transaction with a PO number. This report aggregates the number of electrodes checked in by PO number, so they can see if they have received all of the electrodes to fulfill the PO. Since this list would grow indefinitely, I added a "clear all POs" button as a temporary solution that Updates all records in the transactions table, setting PO = ''.
I want to be able to do this on a per-electrode basis - so you'd have a button next to each of the entries on the report that would allow you to clear the PO field for all of the transaction entries that have Electrode ID equal to the one correlating to the button you push. Any suggestions for a good way to do this?
