On Hand Negative Flag

Select this check box to instruct the system to allow on-hand balances to become a negative number. You will receive a warning message when a negative number is calculated by the system. Clear this check box to instruct the system to prohibit on-hand balances from becoming a negative number.

Note:  There are several scenarios in which an item cannot go negative, even if this field is selected:
  • Serial numbered items cannot go negative.
  • If the reserved quantity plus the contained quantity is greater than zero (qty rsvd + qty contained > 0), then the item cannot go negative.
Caution: 
This box must be selected if the backflushing feature is being used.

The system checks for this flag in these places:

  • Customer Order Entry: When shipping more than is available
  • Purchase Order: When returning more than is available
  • Job Material: When issuing more than is available
  • Stockroom Locations: When:
  • moving too much material
  • adjusting to negative amounts
  • inserting with negative amounts
