Check Material Availability

The material availability can be determined for the service orders, work orders and maintenance sales part delivery and part loan lines, for the defined selection range using the Check Material Availability (tstdm2220m000) session. The results of the ATP, Planned Inventory and On Hand Inventory check are registered in material availability lines, at order, activity and material level. These result can be viewed in the Service Material Availability (tstdm2520m000) session. The results are also displayed on the order, activity and material line.

Note

The material availability check is not performed for orders with status set to 'Free'. The availability lines are removed for closed and canceled orders.

ATP Inventory availability

Available-to-Promise inventory is the item quantity that is currently available and considered for calculating the ATP planned inventory movements such as planned purchase orders. To calculate ATP for an item, the item Order System must be set to Planned in the Items (tcibd0501m000) session.

The ATP check indicates if the required quantity for the given item and the required date and warehouse are available. If there is sufficient inventory, a planned inventory issue transaction must be created to ‘allocate’ the inventory to the order. This planned inventory transaction consumes the planned ATP inventory in the Item Order Plan. If sufficient inventory is not available, Infor LN allocates inventory for the components of the given item or critical work centers.

ATP check can only be performed during planning of the orders. You can perform the check by selecting the Check ATP Inventory check box in the Service Order Resource Planning (tssoc2260m000) and the Planning and Releasing Work Orders (tswcs3200m000) session. This check box is also available in the Release Service Orders (tssoc2200m000) session but is used only when orders are released without first planning. The planning step is performed implicitly.

The results of the ATP inventory availability check in the Service Material Availability (tstdm2520m000) session are:

  • If the Check ATP Inventory check box is selected, ATP inventory check is performed for this material.
  • If the ATP Inventory Available check box is selected, ATP inventory is checked and available on the required delivery date.
  • The ATP Date indicates when the material is expected to be available. This can be the required delivery date when the material is available or a later date when the material is not available.
  • If the ATP Checked on Date is specified, indicates the date and time of the last performed ATP check.
Planned Inventory and On Hand Inventory Availability

The Planned Inventory and On Hand Inventory check is performed when the Check Planned Inventory and the Check On Hand Inventory check boxes are selected in the Check Material Availability (tstdm2220m000) session or during planning or releasing of the order.

Calculating the availability of the On Hand quantity for a specified item:

  • When the ‘scope of inventory’ is selected, the On Hand quantity for an item in the current warehouse only or for all warehouses in the same cluster is considered.
  • When ‘skip blocked inventory’ is selected, the blocked quantity is subtracted from the On Hand quantity.

Depending on the selected ‘scope of inventory’ the Item planned inventory transactions (PIT) for the current warehouse only or for all warehouses in the same cluster are selected.

When calculating the Planned Availability or On Hand Availability for a particular order, the quantities in planned inventory transaction for orders with a higher priority are deducted from the On Hand available quantity. The order priority is determined by:

  1. Non service orders
  2. Released orders by order type based on the Order Type Priority set in the Material Availability group box in the General Service Parameters (tsmdm0100m000) session.
  3. Planned orders by order type based on the Order Type Priority set in the Material Availability group box in the General Service Parameters (tsmdm0100m000) session.
  4. Planned Delivery Date
  5. Order Date

For the On Hand Inventory check, the Current On Hand inventory minus PIT issues is calculated.

For the Planned Available inventory check, the Current On-Hand inventory minus PIT issues plus PIT receipts is calculated.

Material is available when:

  1. On Hand available quantity minus / plus PIT quantity for all orders with higher priority, is positive.
  2. On Hand available quantity minus / plus PIT quantity for orders with earlier Planned Delivery date and higher priority, is positive
Note

Released orders have priority over planned orders. So releasing an order may solve material availability shortage for one order, but causes a shortage on another not yet released order.
