I added and accepted a requisition, but the balance is still negative. Why?

If the requisition’s status is Accepted, the quantity has already moved. The balance may still be negative for one of these reasons: the added quantity is less than the shortage, the requisition is for a different warehouse than the one showing the negative balance, the product or unit is different, or there are outbound transactions after the requisition. To find the cause, open Inventory Detailed Transactions from Reports → Store Reports, select the product and warehouse, leave Type set to All, and check the Stock Level After column after each transaction.
