Internal order settlement to COPA

Dear All,

I have one scenario in which i am allocating manual cost allocation through tcode kb15n.

Sender is I/O and receiver is also I/O and it is done through secondary cost element with cost element category 42.

Now the second step in the above is settlement of above internal orders to COPA (psg) for which settlement rule of above internal orders are defined.

Now i want to settle above internal orders to two value fields in copa for which pa transfer structure is defined and i can only insert one cost element for one value field .

I want to settle on the basis of sender I/O and receiver I/O.

Kindly suggest.

Thanks and Regards,
