ACH CTX processing out of E1 9.0 - anyone using?

We are trying to use E1 to create ACH CTX transactions to our bank and have multiple 'mistakes' in our output, according to the bank. My question is two-fold; Does E1 Support/output NACHA standard formats? Is there any massaging needed to 'vanilla' to the output formats from E1? We are trying to send addenda records (invoices being paid) along with the total payment.

If anyone is using this E1 process and can provide some feedback, that would be great.

TIA

Yes Tim, E1 does support it, to a certain degree, but we found out the bank was actually more competent in assisting us.
And yes, again, you need to massage "the vanilla" (we just cloned it and modified as required).
A year later, a customer is asking us to massage it further.
Let me know if you need further help, in the Developers forum.

We are using it as well. We also had to massage the standard object to meet the banks file layout.
