Issue on validation of cnab240 in banco Itau

[yk2kus]

Hello Danimar,
I exported cnab240 (python3) using this repo. Client validated the file in the bank and got the error "T 3 1 19.06 18:35 19.06 18:35 NAO PROCES

011 SUMMARY OF FILE LINES DIFFER FROM TOTAL REG."

I believe, after fixing this issue there will be more. So I am willing to fix it for Itau. My concern is how do I validate my work? If I give to client and he gets me to return after a day with only. Is there a way I can do my tests and on having issue how do I know which line and which position the issue is?

Thanks in advance.

@danimaribeiro looking to hear from you.

You have to send the file to the bank, get the errors from them and fix, after that send it again.
Keep doing that until you finish the errors.

You have to look at the manual, the only way.
