More then one UOM should come in Invoice and Print output

Hi,

In export sale the unit of measure we sell the goods is in pack. While in domestic we sell this in Pices.we have maintained unit conversion in master data.(for eg 1 pack= 10 pc).In VF01 the requirement is that both units should come.and the same we can print in Invoice for duty draw back purpose.

Order qty= 10 Packs

Invoiced qty = 10 Packs

100 Pc

How can i fetch the other unit . I have already searched SMEINH and MARA tables but unable to find the Conversion units.

Regards

JP
