Decimal places allowed for UoM EA, DZ etc.

Hello,

We had an issue where in user has posted GR with decimal quantity for UoM DZ - Dozen. When I checked the config for DZ in CUNI, there is no "Decimal pl. rounding" value maintained. But still user could able to post GR with Decimal quantity. We are having ECC 6.0 (EPH 6) system.

Does anyone has any idea, apart from this config is there anything else that can allow user to post GR with Decimal quantity for DZ, EA etc?

Thanks,
