Hi
Negative Inventory is not like Multi Currency or Multi Location in that even if you have used it extensively, you can at any time 'turn it off'. Once turned off, you can upgrade your file to AR2018.
To turn off Multi Currency or Multi Location reuqires specialist assistance, to turn off 'Negative Inventory' normally does not.
To turn it off the preference you must restore all item on hand counts to 0 or higher - use Inventory Value Reconciliation report exported to excel to highlight negative on hand counts. Once 'fixed' this will finalise any 'negative inventory' sales and allow you (in most cases) to turn off the preference.
There are 2 exceptions:
- Any Purchase Orders with a 'Received' tick must also be converted to a Bill.
- If you have done all this and still cannot turn off the negative inventory preference, you may require specialist assistance. Send me a private message if you require specialist assistance.
Regards
Gavin
