Inventory blocking is part of the quality inspection process. During the quality inspection, items are automatically blocked from consumption or issue. Also, you can manually block items that you want to prevent from being issued or consumed.
Inventory blocking methods
You can block inventory items in one of three ways.
By creating a quality order
By using a process that generates a quality order
Block items manually
You can block a quantity of an item by creating a transaction in the Inventory blocking form. Only items that are available as on-hand inventory can be blocked.
For manually blocked quantities, you must consider if expected receipts should be included in planning activities as an expected on-hand quantity. Expected receipts are blocked items that are expected to be available as on-hand inventory after inspection. For items blocked through a quality order, the Expected receipts check box is by default selected.
You can cancel blocking of a manually blocked quantity by deleting the transaction in the Inventory blocking form.
Block items by creating a quality order
You can specify items for inspection by creating a quality order in the Quality orders form. When you create a quality order, the quantity of an item that you specify is blocked.
The sampling plan associated with a quality order controls the quantity of an item that should be inspected. The quantity of blocked items, on the other hand, is not controlled by the sampling plan. Regardless of the quantity that is sent for inspection, as specified by the sampling plan, the quantity of the item that is entered on the quality order is the quantity that is blocked.
Block items by a process that generates a quality order
A quantity of an item that is specified for inspection through a quality process is automatically blocked. So when a quality order is generated automatically, the item sampling plan that is associated with the quality order controls the quantity of items that is blocked and not only the quantity of items to be inspected.
If the Full blocking check box in the Item sampling form is selected, the full quantity of, for example, a purchase order line is blocked during inspection regardless of the item sampling quantity.
In the following example, a quality order is generated when a purchase order packing slip is posted. In the Quality associations form, posting of a purchase order packing slip is specified as the process that activates the quality order.
A quality association specifies that upon posting of a purchase order packing slip a quality order must be generated.
The item sampling setup of the quality order specifies that 10% of the purchase order line quantity must be inspected.
Furthermore, with the Full blocking check box selected the item sampling setup indicates that the full quantity of the purchase order line must be blocked during inspection regardless of the quantity that is sent for inspection.
The packing slip is posted.
A quality order is generated.
10 % of the purchase order quantity of the item is sent to inspection.
The full quantity of the purchase order line is blocked.
