Can we change the "Qty on PO" field in each inventory?

Hello @kit_wong,

As of the moment, there isn't an integrated way to changed the information of your inventory items under the Qty on PO column. 

With this, let's consider reviewing all the open purchase orders associated with each item to determine and change this information. Let me show you how.

1. Go to Expenses.
2. Select Filter.
3. Under Type, select Purchase Oder.
4. Click Apply.

From here, you can open and review the item associated with the purchase order to change it.

Additionally, I've also included this reference for a compilation of articles you can use while working with us: Help Articles for QuickBooks Online.

If you have any other questions, please let me know in the comments below. I'll be here to lend a hand.
