Background: Component Availability Inquiry
Use the Component Availability Inquiry (MOS) program to display the requirements for a proposed manufacturing order against current supplies of components. You can see immediately whether you have sufficient inventory to release the order or how you might adjust it to use what is available. See Road Map for work flow.
Calculations
The Compare order qty against avl or on hand determines whether shortages are based on the on hand or available quantity. If you select A Compare order qty to available, you also need to choose how available quantities are calculated.
The Calc available using obligated/committed Program option lets you choose: On hand + Floor stock - Obligated or On hand + Floor stock - Committed.
The example that follows abbreviates the options for simplicity:
Example:
A level 1 component has a calculated qty required = 10.00000 with on hand = 7, committed = 3 and obligated = 1
When the Compare option is set to On hand, the qty required for its level 2 components is 3.00000 (10 required – 7 on hand)
When the Compare option is set to Available and:
the Calc available option is set to Committed, the qty required for its level 2 components is 6.00000:
10 required - 4 available (available = 7 on hand - 3 committed)the Calc available option is set to Obligated, the qty required for its level 2 components is 4.00000:
10 required - 6 available (available = 7 on hand - 1 obligated)
If you selected the Only display components with shortages? program option the report only includes components with shortages.
Critical Lead Time
The program calculates critical lead time as the lead time for the parent item plus the longest lead times of any components that are in short supply at each level of the bill of material.
