Unconstrained SP: Lead time calculation and due date logic for supplier operations (OSP)
Summary:
Hello,
Could someone help me understand how supply planning works for Outside Processing operations.
Item A has four components: B, C, D, and E. The work definitions are as follows:
Since each resource's assigned unit is 1 and the shift is 8 hours, OP10, OP20, and OP40 each require one day.
Operation | Type | Operation Item | Operation Resource | Resource Usage (Variable) | Supplier Operation LT (Variable) |
|---|---|---|---|---|---|
OP10 | In-house | B | R1 | 8 Hours | |
OP20 | In-house | C | R2 | 8 Hours | |
OP30 | Supplier | D | 8 Hours (1/3 day) | ||
OP40 | In-house | E | R3 | 8 Hours |
- When I run "Calculate Lead Times and Roll Up Cumulative Lead Times," the variable lead time for item A is 3 days.
