As the components and the assemblies are needed for the production of a higher-level planned order, they must be available by the order start date of this higher-level planned order.

Use the distribution function if the complete quantity of dependent requirements for a particular component is not needed on the order start date, but is to be delivered throughout the production process (between the order start and order finish dates). The dependent requirements quantity determined from the BOM explosion is then distributed between the order start date and the order finish date.

You define the distribution key for splitting component consumption in the BOM.

You can find further information on adapting scheduling to the operations in the SAP document PP - Routings.

You can find further information on the distribution function in the SAP document PP - Repetitive Manufacturing.

In situations where orders have long lead times, the calculation of dependent requirements dates can result in components being provided much earlier than they are actually needed in the production process. To avoid this situation, the dependent requirements date of the subordinate components can be rescheduled by the lead-time offset.

You have determined the lead-time offset in the BOM by entering the number of workdays by which the staging of components is to be displaced in the Lead time offset field in the item overview screen.

If you enter a positive value, the dependent requirements date of the component is displaced into the future by this value, starting from the order start date of the assembly’s planned order.

If you enter a negative value, the dependent requirements date will be brought forward.
