Hello!
Can you please specify where exactly do you see the value 002 in bank statement on FEBAN? Can you please attach the screenshot?
Well anyway, there are several options available:
a) if you didn't change the screen layout in FEBAN, then you might mistakenly conceive internally defined posting rule 002 (if you have such a rule) as BTC code, because in FEBAN if you didn't applied any changes to standard layout you don't see the BTC code, but posting rule;
b) as far as I remember, you have configured search string for the word "comision" and BTC code 035, if that's the case the system will post the line item from bank statement using the posting rule specified under search string settings, please check.
Hope this will help!
