Andy,
Finally! I was able to resolve this with AMC Banking. Here is my final post on their support site:
Piotr,
I took your advice and deleted the records relating to AMC Banking in the Data Exchange Definition, Bank Import/Export, and Payment Methods tables. These were the codes of the deleted records:
(*BANKDATACONVSERVCT, BANKDATACONVSERVSTMT for Data Exchange Definitions and Bank Import/Export)
(*BNKCONVDOM and BNKCONVINT for Payment Methods)
Then I deleted the batch in the payment journal that I had been using. Next I used the default payment journal batch and voila! I was able to export an EFT file. Thanks for your help.
I still am stuck with a line in the assisted setup table that refers to AMC Banking Foundation Extension, which is not possible to delete. It doesn't interfere with creating Export Files of payments.
You may close this ticket
Sincerely,
Steve
