To block and unblock

You can block the inbound movement, outbound movement, transfer (receipt, issue), or assembly of items in these ways:

  • By blocking stock points
  • By blocking inbound and outbound types of transaction.

Blocking stock points

A stock point block blocks these types of transaction for the affected stock points:

  • Inbound movement
  • Outbound movement
  • Transfer (receipt, issue)
  • Assembly

Also, a stock point block increases the quantity of the inventory on hold and decreases the quantity of the inventory available.

When you impose a stock point block, you must specify a reason code of either of these types:

  • Inventory Blocking excluding EP

    Enterprise Planning can ignore the block and regard the blocked stock points as available inventory.

  • Inventory Blocking including EP

    The blocked stock points are unavailable for planning.

To impose stock point blockings, you can block any of these objects:

  • Zone

    The stock points stored in the locations of the zone are blocked.

  • Location

    The stock points of the location are blocked.

  • Lot

    The stock points of the lot are blocked.

  • Stock point

    The stock point and, if present, the serial numbers of the stock point are blocked.

  • Serialized item

    Specific serial numbers of partially blocked stock points are blocked.

  • Handling unit

    The stock points contained in the handling unit are blocked. If the handling units has child handling units, LN blocks the child handling units and the stock points contained in the child handling units.

After blocking a zone, location, lot, handling unit, or stock point, the resulting blocked stock points are displayed in the Blocked Stock Points (whwmd6550m000) session.

Partial stock point blockings

You can impose partial blockings on a stock point. For example, a stock point has a total on hand quantity of 20. A user imposes a manual blocking for 10 items for reason A on this stock point.

Multiple blockings for the same stock points

Various blockings can affect the same stock point. For example, a stock point contains 20 items and you impose a partial blocking of 5 items, a partial blocking of 3 items, and another partial blocking of 7 items. Or a user imposes a partial blocking on a stock point, and, later on, another user blocks the location in which the stock point is stored.

Updating the stock-point blocked inventory

A stock point block increases the quantity of the inventory on hold and decreases the quantity of the inventory available.

After blocking a stock point, the entire inventory of the stock point is blocked. If a partial blocking is imposed on a stock point, the blocked inventory of the stock point is increased by the quantity of the partial blocking.

If multiple partial blockings are imposed on a stock point, the blocked inventory of the stock point can be updated in these ways:

  • Increase the blocked inventory with the aggregated quantities of the partial blockings.
  • Increase the blocked inventory by the quantity of the largest partial blocking. For example, a stock point contains 20 items and you impose a partial blocking of 5 items and a partial blocking of 3 items. The blocked inventory is increased by 5.

The settings of these check boxes are used to control the way the blocked inventory is updated:

  • Allow Overlapping Stock Point Blocking parameter in the Warehouse Master Data Parameters (whwmd0100s000) session and the Warehousing Settings by Site (whwmd2101m000) session.
  • Overlapping in the Stock Point Blocking (whwmd6130m000) session.

Blocking project pegged inventory

If you block a zone, location, lot, handling unit, or stock point, the project pegged inventory contained in these objects is also blocked.

Blocking transactions

A transaction block is a block imposed on transactions of these types:

  • Inbound movement
  • Outbound movement
  • Transfer (receipt, issue)
  • Assembly

If you block specific types of transactions, the inventory on hold of the affected items is not increased. The inventory is just blocked for inbound, outbound, assembly, or transshipment.

With transaction blocks, no individual stock points are blocked, and there is no impact on the inventory levels or on Enterprise Planning.

You can impose transaction blocks on these objects:

  • Warehouse
  • Zone
  • Location
  • Lot
  • Stock point

Blocking warehouses for inbound and outbound transactions

You can block a warehouse for all inbound transactions, all outbound transactions, or both. A block on a warehouse is either full or interactive. Full block means that no transactions are allowed. Interactive means that the user can manually override some of the blocks on inbound or outbound transactions.

Blocking transactions for zones, locations, lots, and stock points

For zones, location, lots, and stock points, you can impose a transaction block for each type of transaction. For these objects, interactive blocks are unavailable.

A full or an interactive block imposed on a warehouse also applies to any zones or locations of the warehouse. If the warehouse is blocked for inbound transactions, the zones and locations of the warehouse that accommodate receipts are also blocked. Similarly, a warehouse blocking on outbound transactions blocks the zones or locations for outbound transactions.

If a warehouse is not blocked for inbound transactions, you can impose inbound blocks on the zones and locations of the warehouse, and if a warehouse is not blocked for outbound transactions, you can impose outbound blocks on the zones and locations.

Similarly, blockings set for zones override those set for locations. If a zone is blocked for a type of transaction, the locations of the zone are also blocked for this type of transaction.
