F110 and Bank Determination Problem

Hi Expert,

I have problem / question on the bank determination problem on F110, as follows:

My Payment method (PM): N

Ranking order for PM: N is:

Rank 1: House Bank is ... ABMB

Rank 2: ABMB2

Rank 3: ABMB3

....

Rank 15: MBB

In my F110, at my setting for printout/data medium, variant created (Program: RFFOD__S) for PM:N and for House Bank: MBB (Not ABMB).

Question:

I have vendor open items of PM:N, and when I run the F110 (using the above setting / variant) , why SAP always clear the open items using house bank ABMB, and not MBB? I expect F110 will use house bank MBB, as I set variant for program: RFFOD__S is MBB for PM:N.

Thanks in advance for your help.

Regards,
