Requirements Planning: Calculation of the Quantity Required of Header Article from the Component Quantities

Use

This function calculates the quantity required for a header article of a structured article from the quantities required of the constituent components.

You can incorporate your own method of calculation using User Exit WSOS0001 and component EXIT_SAPLWSOS_001. If you do not use your own method of calculation , the system calculates the quantity required for a header article using the mean value method, as explained in the following example:

Example

A display consists of the following:

Component

BOM quantity

Component 1

10

Component 2

20

Component 3

30

The consumption figures for the components are as follows:

Component

Consumption

Component 1

90

Component 2

160

Component 3

210

For every component, a certain number of displays are required to replace the quantity consumed. This number is the consumption figures for each component divided by the quantity of each individual component in the bill of material of the structured article.

Component	Consumption	BOM quantity	Required Displays
Component 1	90	10	90 / 10 = 9
Component 2	160	20	160 / 20 = 8
Component 3	210	30	210 / 30 = 7

The mean value of all the components is taken as the number of displays required:

Mean value for the number of displays required = (9 + 8 + 7) / 3 = 24 / 3 = 8

If decimal places appear in the calculation, the system rounds down under 0.5, otherwise it rounds up.

Integration

This function is used in the following areas:

· Requirements planning

in time-phased planning of components of a structured article

· Replenishment

in the planning of replenishments for components of a structured article

· Allocation

in allocations using replenishment allocation strategies where structured articles are involved.
