How can we prevent requester creating requisition for items having enough on hand?

Summary:

We have requirement from a mining client where they stock items in inventory, and they want to restrict/prevent requesters to raise the requisition of items for which they already have on hand stock in inventory.

We have already proposed for requesters to attach the item on hand screenshot as requisition justification for the approver to verify and approve (in case of lack of stock/reject (in case of enough stock).

Use Case:

1. Item=ABC, Stored in Warehouse=A1, Item On hand of item ABC=100
2. Requester Mr X, created internal requisition for Item=ABC and doesn't check the onhand before raising requisition. This PR would be approved , convert to PO and delivered.
