Use

Material can flow directly from goods receipt into consumption/usage or into the warehouse. However, It may also be placed into a blocked stock area first.

Using the stock type, you can post the material into quality inspection stock or into blocked stock. In both cases, the material is already managed in the stock. Alternatively, the material can be conditionally accepted. Conditionally accepted deliveries for a purchase order are recorded in goods receipt blocked stock (GR blocked stock).

The quantity posted into goods receipt blocked stock is not added to the inventory or managed as part of the inventory. It is only recorded in the purchase order history.

You would use goods receipt blocked stock, for example, if the vendor's certificate for the delivered quantity were missing, or if you wanted to inspect a small quantity of the material before posting the actual goods receipt.

When the conditions for acceptance are met, the material can be accepted into stock (for example, into unrestricted-use stock). The goods receipt is not valuated until this point.

If the goods are to be returned to the vendor, instead, they can be taken directly from goods receipt blocked stock. Note, however, that a return delivery is possible even if the material was already posted into stock.
