Item selection in order planning, examples

This section presents several examples of the selection of plan items to plan in the Generate Order Planning (cprrp1210m000) session and the Generate Order Planning (Item) (cprrp1220m000) session.

For the general description, refer to RRP run, item selection.

Example 1: item selection and anonymous items

You plan a plan item, called X. The X item is part of the following multilevel BOM:

[...]

The A item is a project item. All the other items are anonymous items.

If you select the Use Bottom-Up Item Selection check box, LN plans the following items: A, B, and X.

If you select the Use Top-Down Item Selection check box, LN plans the following items: X, E, F, and G.

Example 2: item selection and project items

You plan a plan item called Y. Item Y* is derived from Y. The Y item is part of the following multilevel BOM:

[...]

The M item is an anonymous item. The other items are project items.

If you select the Use Bottom-Up Item Selection check box, LN plans the following items: Y, K, Y*, and K*.

If you select the Use Top-Down Item Selection check box, LN plans the following items: Y and M.

If you select the project item Y*, and select the Use Top-Down Item Selection check box, LN plans the following items: Y*, M, N, and Y

Example 3: item selection and supplying relationships

You plan a clustered plan item called Z(Ah). Item Z(Ah) is part of the following multilevel BOM, and of the following distribution network:

[...]
Z AhItem Z in the assembly hall
Z CsItem Z in the central storage
Z DcItem Z in the distribution center
Z StItem Z in the store
Q CwComponent Q in the central warehouse
Q AhComponent Q in the assembly hall
R CwComponent R in the central warehouse
R AhComponent R in the assembly hall

Item Z, Q, and R are normal items. The dashed arrows in the figure indicate the supplying relationships between the clustered plan items.

If you select the Use Bottom-Up Item Selection check box, LN generates the order planning for the following items:

Planned ItemReason
Z AhThe item that you selected yourself
Z CsReceiving item of Z Ah
Z DcReceiving item of Z Cs
Z StReceiving item of Z Dc

 

If you select the Use Top-Down Item Selection check box, LN generates orders for the following items:

Planned ItemReason
Z AhThe item that you selected yourself
Q AhComponent of Z Ah
Q CwSupplying item of Q Ah
R AhComponent of Z Ah
R CwSupplying item of R Ah

 

Example 4: Item selection and alternatives

In the BOM for item A, you have defined item M as an alternative for component X.

The same item M is used as a standard component in the BOM for item K.

[...]

If you plan item X and you select the Use Bottom-Up Item Selection check box and the Use Top-Down Item Selection check box, LN generates orders for the following items:

Planned ItemReason
XThe item that you selected yourself
MThe alternative for X
AThe main item of X
DComponent of X

 

If you plan item M and you select the Use Bottom-Up Item Selection check box and the Use Top-Down Item Selection check box, LN generates orders for the following items:

Planned ItemReason

KThe main item of M
N, OComponents of M
