Negative on Picking

How do I prevent inventory to go negative when generating a Pick List.

I have the Pick negative option disabled on the Production Control Parameters but its till letting me pick and ship an item with no inventory.

Thanks

Hi,

Check in Item Model Groups weather the Physical Negative Inventory is checked or not.

Then please check the Item Type is not Service

Uncheck the check box “Pick negative” under production>setup>parameters>journals> Pick negative

That did it.
