Scenario: Node type location aggregate in network availability safety stock

You can create network safety stock rules with nodetype override values that is applied to all nodes within the distribution group when location aggregation is enabled. When you apply the node location aggregate for the network safety stock rule, the node level safety stock that belongs to the target network must be provided.

Example 1

Consider the following inventory availability.
Node Supply quantity
N1 - store 5 quantity
N2 - distribution center 6 quantity
N3 - distribution center 10 quantity
Assume the inventory for two networks: DG1 and DG2 with the following nodes.
Distribution group Nodes
DG1 N1, N2, N3
DG2 N1, N2, N3
The total network availability is 21 qty.

If you enable node type of DC location aggregate for DG1 at 20 quantity, the availability is N1 + (N2|N3-20) = 5 + |-4| = 5.

In this case, the safety stock value is set at the aggregate that is greater than actual supply so the availability for DC is not zero. However N1- store that is part of the network is not impacted.
Note: The node type aggregate overrides any safety stock settings that is applied at the individuals nodes - N2 or N3 and gets overridden.
When the node type aggregates is configured, the system evaluates all the node safety stock that are not part of the node type and then aggregates with the node level safety stock.

Example 2

Consider the following inventory setup:
Nodes Supply quantity
N1 - store 5 quantity
N2 - distribution center 6 quantity
N3 - distribution center 10 quantity
Assume two networks DG1 and DG2 with the following nodes.
Distribution groups Nodes
DG1 N1, N2, N3
DG2 N1, N2, N3
Consider the following safety stock for the nodes:
Node Safety stock
N1 1
N2 2
N3 3
The total network availability is 21 qty.
Consider DG1 with node aggregation enabled and node type aggregate safety stock for distribution center at 100%. The system evaluates the following results:
  • The node aggregate safety stock = N1_SS + N2_SS + N3_SS = 6
  • The node type safety stock is (N2+N3)@100% = 16qty
The DG1 safety stock is calculated as N1_SS + DC_SS = 1 + 16 = 17.

Since the node type aggregate always overrides the node level safety stock, the 17 quantity of safety stock is withheld.

Example 3: Rounding of percentage value in location aggregate

Consider the network supply for DG1 is 17 quantity.

Consider network rule for distribution group DG1 with location aggregate for store node type enabled and a safety stock of 80% defined with rounding down. This results in 13.6 safety stock to withhold. This value is rounded down to 13 quantity.

Hence, available to sell for DG1 is 17-13 = 4 quantity.
