Yes I have and I'm getting a NoCanDo from both sides. I've asked each party if there are zero GP users sending EFT files to HSBC but of course no one knows what source an EFT file comes from. I've ask the HSBC EFT coordinator to ask the bank's IT department if they've developed a pre-import process that alters the date format automatically.
I'm desperately hoping I won't have to tell my client that their new GP 2013 system can't connect an EFT payment file with their new bank. Two billion dollar companies and they have incompatible date and time formats? Seems unbelievable.
In the end my client can open the EFT file each time and insert slashes and colons, etc. but that's a horrible process to tell someone about that just spent $125,000 on a new world-class ERP system.
