The quantity on inventory is not sufficient to cover the net change in inventory.

Hi all!

When you enter the quantity field in sales documents or output item journal lines, the program can warns you if there are not enough items on inventory:

The quantity on inventory is not sufficient to cover the net change in inventory. Do you still want to record the quantity?

If you want to set up it you only need to select the "Stockout Warning" check box in the "Sales & Receivables Setup" page:

The warning is based on a calculation that sums quantity on inventory and unposted sales order lines, including reserved quantities and considering location code.

Hope be useful!
Bye! ;)
