We are in the process of testing an upgrade of GP 2010 to 2015. I am verifying all our integrations will continue to work. One that is failing is a cash receipts integration. I have not modified it at all from 2010 to 2015. The integration maps the following fields:
Batch ID
Date
Posting Date
Customer ID
Cash Receipt Type (CC)
Amount
Checkbook ID
Check/Card Number
When I run this integration using IM 2015 it fails for customers who do not have a Credit Card ID assigned in the Customer Maintenance Options window, even though I'm passing it in the integration. This was never a problem in 2010. Do I need to mass update all my customer records with a credit card ID? What will happen then if a different credit card is used for a particular transaction? Why doesn't the same integration work in 2015?
