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 transactions.
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:

  • The stock points stored in the locations of the zone are blocked.
  • The stock points of the location are blocked.
  • The stock points of the lot are blocked.
  • The stock point and, if present, the serial numbers of the stock point are blocked.
  • Specific serial numbers of partially blocked stock points are blocked.
  • 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.

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. See Manual blocking and project pegged inventory.

Multiple blocks for the same stock points

Various blockings can affect the same stock points. In such cases, the highest blocked stock-point quantity prevails.

Example

A user manually blocks a location. Among various other items, this location holds 6 pieces of a particular lot. Another user then blocks the lot, which has a total quantity of 25. Of the blocked quantities for the lot, 25 is the higher. Therefore, LN sets the blocked stock point quantity for the lot to 25.

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:

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.
