Sage 100

Customer is on 2014-5.10.6 Advanced using SPS. According to the customer, in a prior version of Sage, they would get a warning if they entered a credit card number into the system that was a duplicate number. With this version, they are not getting a warning. Does this feature come back in 2015 or 2016?

I don't remember that in any version. Was is maybe pre SPS? Like a function of PC Charge or something. The only popup I remember is the one that tells you the credit card and the amount are the same, indicating the transaction was being processed twice. Nothing about a credit card number being a duplicate. https://support.sagepayments.com/link/portal/20000/20000/Article/3246/Error-Duplicate-Transaction
