Posted on by GK-08101819-0

Hi everyone,

Getting this error message when I try to generate an EFT file : Transit Routing No. must have a value in ACH RB Detail: Data Exch. Entry No.=3, Data Exch. Line Def Code=DETAIL. It cannot be zero or empty.

I had no issue sending out payments last week. Issue just started.

I checked the country code and ISO code on the vendor bank card of these vendors and they are all correct.

How can I sort out this issue please?

Please check the vendor bank account for the Transit Routing No., it seems like that is the value it used on the EFT

EFT File Generation - Error

Hi,

This error might occur because Business Central requires the Transit Routing Number (bank routing number) to be populated for ACH/EFT exports. This value is pulled from the Vendor Bank Account card and mapped through the Data Exchange Definition for the EFT file.
Check Vendor Bank Account Card

Navigate to Vendor → Bank Accounts.

Ensure:

Transit No. (Routing Number) is entered.

Use for Electronic Payments is enabled.

If the routing number is missing, add it.

Hi,

The error means the Transit Routing No. field is missing for the vendor’s bank account. ACH EFT files require this value.
Try:

> Open the vendor’s Bank Account Card.
> Enter the correct Transit Routing No..
> Verify the ACH Data Exchange Definition mapping.

Without this, EFT generation will fail.

Thanks

When you sent out payments last week, were they to the same vendors? If they were, the issue likely isn’t a missing transit number. If the vendors were different, double-check whether one of them might have a missing transit number.

If all transit numbers are present, it could be a bug. Was your Business Central environment updated between last week and this week? If so, what version are you on?
