Credit Memo and Standard Invoice on Payment File

Hi,

I created a Payment Batch including a Standard Invoice (100 SEK) and a Credit Memo (-25 SEK) for the same supplier. At the 'Review Proposed Payments' screens it is showing as a netted amount of (100-25=) 75 SEK, however when I create the (Swedish Bankgiro Inland) payment file it is showing as two separate lines (100 and -25). Since SEB Bank is not accepting the negative amount, we would like to have just one line with the sum of both documents (75 SEK).

Can someone please advice if this is an Oracle setting related issue or something on the Payment format?

Thank you.
