How to sell reserved goods

Situation:

Accounting policy: Inventory valuation method = FIFO, Debit note document posts all entries.

We post a sales order with 10 million pcs of a product. Based on the sales order, we post a purchase order with 5 million pcs of the product, we post a supplier invoice with 5 million pieces of the product, and then we reserve the goods for the sales order.

Then in order to return a part of the purchased goodes, we post a debit note with the Purchase return operation type with 1 million pcs. The warehouse stores the remaining 4 million pcs.

Based on the sales order, we register a sales of a portion of the remaining goods: we try to post a sales invoice with 1 million pcs and 1C:Drive does not allow us to do this this because of the lack of the goods in the warehouse.

Solution:

To return 1 million pcs of the goods, first you should clear the reservation of 5 million pcs (Inventory reservation), then return the goods to the supplier. As a result, you will be able to sell the remaining 4 million pcs. Alternatively, you can use the inventory reservation document to clear reservation of the excessive reserve.
