Bank Statement in BAI2 format related

Hello,

We are on Oracle R12.1.3.  This question is related to bank statement which we require to load in R12 using BAI2 format.

I have created Bank transaction codes (supplied by bank, so they are custom transaction codes) for  BAI2 format.  I am able to load bank statement successfully in R12.

Issues:

1.) Control Totals >> Receipts and Payment amounts and Line Totals >> Receipts and Payments amount are exactly opposite.  What I mean is amount balance for Control Totals >> Receipts = Line Totals > Payments and vice versa.  Any idea why it is behaving in this way?  See screenshot for detail.

2.) Does "Bank Statement Import" program consider custom bank transaction for Control Totals >> Receipts and Payments or it considers standard transaction codes for same?
