We weren't using Merchant ID's in tr_pmt_method_group, but were using them for grouping tr_payment_method entries. Now we're moving to Payment Express and tr_pmt_method_group entries need a Merchant ID, but the some of the groups contain payment methods with different Merchant ID's. For example: Payment Method Group 26 is composed of Payment Methods Box Office and Web, but the Merchant ID for Box Office is 999 and the Merchant ID for Web is 888. So what do I put in as the Merchant ID for Payment Method Group 26? 999 or 888? Does it really matter? Or do I need to create separate Payment Method Groups?
Any help would be appreciated.
