Combo Edit for PCard

I've been trying to set up a combo edit that would make some account values invalid on PCard transactions.  For example, we have users that are selecting balance sheet accounts, or payroll accounts.  This creates additional work along the way for processors and administrators.

I set up a combo edit that would mark a combination invalid if a group of Account codes was not used.  I applied this combo edit in Ledgers for a Unit.  I selected Specific Transaction Source and then selected "Purchasing ProCard Transaction."

When we go into a statement through Main Menu > Purchasing > Procurement Cards > Reconcile > Reconcile Statement, we are able to change the account to an invalid account on a transaction line and save without getting a combo-edit error.
