On the payment schedule tab, remove all lines and let the system fill in that record.

I did delete the payment schedule line and get another error. "You must enter at least one detail and amount before you can add the transaction"

My apologies I forgot to include item number CNTITEM in invoice details. It works fine now thank you.

The detail is empty, or your CNTBTCH/CNTITEM values  aren't the same on header and detail tabs.

it had a value of zero (0) for CNTITEM in invoice details.

make all of the CNTxxxx values "1" on all tabs.

Not working still getting error? Document total are correct but still getting error.
