Free goods for line level adjustment on item group

Hi there,

I got the following scenario where I would like to use JDE advanced pricing:

Setup a line level adjustment based on advanced item group on SRP2 called ABC. Let's say that we have 10 items that have SRP2=ABC:

ITEM1 ABC

ITEM2 ABC

ITEM3 ABC

ITEM4 ABC

ITEM5 ABC

ITEM6 ABC

ITEM7 ABC

ITEM8 ABC

ITEM9 ABC

ITEM10 ABC

The request is to give a free good for each 10 only of the items that is part of the SO, i.e.:

ORDER1

ITEM1 10

ITEM3 10

ITEM5 10

ITEM1 1

ITEM3 1

ITEM5 1

ORDER2

ITEM2 10

ITEM6 10

ITEM7 10

ITEM2 1

ITEM6 1

ITEM7 1

I think the only way is to change the adjsutment setup and make it by item and not by item/group, but it will require lot of maintenance.
