| # Phantoms of generic items In regular order-based planning, phantoms are treated in the following way: The phantom is replaced by the components in its BOM The phantom's routing is treated as part of the existing routing If a generic item G has a phantom, the phantom's components and operations are offset relative to the planned order finish date of G. The way in which this is done depends on whether the phantom itself is a generic item or a normal item. Below you will find an example of both situations. Example: generic phantoms of generic items Consider the following situation: A generic item G1 has a generic phantom G2 G2's generic BOM contains a (normal) component N3 G2's generic routing contains one operation OP In this situation, the planning proceeds according to the following diagram:
A | Offset of N3 in G-BOM of G2
B | Offset of G2 in G-BOM of G1
C | N3 finish date of G1 order
D | Offset of OP in G-ROU of G2
E | Offset of G2 in G-BOM of G1
F | OP1
G | OP2
Example: normal phantoms of generic items Consider the following situation: A generic item G1 has a normal phantom N2 N2's BOM contains a (normal) component N3 N2's routing contains operations OP1 and OP2 In this situation, the planning proceeds according to the following diagram: (1) Offset of N3 in BOM of N2, Or:
A | Order lead-time of N2
B | Offset of N2 in G-BOM of G1
C | N3 finish date of G1 order
D | Order lead-time of N2
E | Offset of N2 in G-BOM of G1
F | OP1
G | OP2
Remarks: If an offset is specified in N2's BOM, this offset is used to offset N3; otherwise, N2's order lead-time is used. In a normal routing, no offset is available; instead, N2's order lead-time is used to offset N2's operations. Note You can specify an item's order lead-time in the Items - Production (tiipd0101m000) session. Related topics Generic items in Enterprise Planning |
