Error message when posting an invoice in Business Central

Hello!

I am not able to post an invoice due to an error that I keep getting from Business Central. Never faced this issue before : The Payment Method does not exist. Identification fields and values: Code=''

For every other vendor there has never been such error therefore not sure how to solve it.

Maybe someone faced the same issue before?

Thank you in advance for any help!

Hello,

This error means Business Central is trying to validate a Payment Method Code that is mandatory but empty (Code = ‘’), usually only for that specific vendor. Check the Vendor Card → Payments FastTab and either set a valid Payment Method Code or ensure it’s not required by setup. Also verify the Purchase Invoice header (it can override the vendor) and Purchases & Payables Setup / Vendor Posting Group, as customizations or localizations may enforce payment methods. This typically happens with copied or imported vendors where the field looks empty but is still required.

Is this due to customization? As far as I know, Payment Method is not a required field.

Hi,

I think this is some customization where you are flowing some values from Purchase Header to some other table.

However you can try following to solve the issue.

1 - Check Vendor Master and if on the vendor master in Payment tab Payment method code is blank, define it.

2 - Check Purchase Invoice or Purchase order document header part - Payment method code field, if blank then define it.

Usually this shall solve the issue. But make sure you handle this customization to show appropriate error that user can understand easily.

Regards,

Dhiren.

Hey,

It simply means that "Payment Method Code" is blank somewhere, maybe in the selected Vendor or may be in the Document.

Best thing to do is to copy the Production environment into a sandbox and apply debugger to find the exact root cause.

Also, you can Copy Error details from the Analysis view to get the error stack to track the origin of the error.

Hope this helps.
