| 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. This topic contains the following examples: Example 1: Item selection and anonymous items Example 2: Item selection and project items Example 3: Item selection and supplying relationships Example 4: Item selection and alternatives 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, ERP LN plans the following items: A, B, and X. If you select the Use Top-Down Item Selection check box, ERP 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, ERP LN plans the following items: Y, K, Y*, and K*. If you select the Use Top-Down Item Selection check box, ERP 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, ERP 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 Ah | Item Z in the assembly hall
Z Cs | Item Z in the central storage
Z Dc | Item Z in the distribution center
Z St | Item Z in the store
Q Cw | Component Q in the central warehouse
Q Ah | Component Q in the assembly hall
R Cw | Component R in the central warehouse
R Ah | Component 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, ERP LN generates the order planning for the following items:
Planned Item | Reason
Z Ah | The item that you selected yourself
Z Cs | Receiving item of Z Ah
Z Dc | Receiving item of Z Cs
Z St | Receiving item of Z Dc
If you select the Use Top-Down Item Selection check box, ERP LN generates orders for the following items:
Planned Item | Reason
Z Ah | The item that you selected yourself
Q Ah | Component of Z Ah
Q Cw | Supplying item of Q Ah
R Ah | Component of Z Ah
R Cw | Supplying 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, ERP LN generates orders for the following items:
Planned Item | Reason
X | The item that you selected yourself
M | The alternative for X
A | The main item of X
D | Component 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, ERP LN generates orders for the following items:
Planned Item | Reason
