Rounding in Purchase Order with multiple materials

Hi All,

I’m trying to find a solution for my problem and so far no luck. Here’s the situation:

My client orders multiple materials from one vendor and these material are being shipped in a container. The challenge here is to fill up the container.

For instance:

There are  Purchase Req. for:

1.      10 PC of material X
2.      20 PC of material Y

The container capacity is 1 M2 (where M2 is some UoM). For both materials X and Y  ,  1 M2 = 60 PC.

My client wants to ship in full containers only. I tried to use rounding profile (static and dynamic), but SAP always rounds up each line separately, so I get a full container for each material (PO is created for 60 PC of X and 60 PC of Y).   It should be 20 PC of X and 40 PC  of Y.

I would like to know is there any standard solution so SAP will look at all items in PO during rounding?

Thank You!

Best Regards,

Marek
