Distribution Key
In this field, you can enter the distribution key for dividing up dependent requirements or reservations for this component over time.
In Customizing for Production, you define distribution functions by choosing Repetitive manufacturing
If you enter a distribution function for a component, portions of the dependent requirement are distributed over the runtime of the planned or production order in accordance with the distribution function.
This means that dependent requirements are not available in full on the order start date. Instead, they are brought into the production process continuously between the order start date and the order finish date.
The last portion of the dependent requirement must be available at the latest on the finish date of the assembly.
If, for example, the last portion of a dependent requirement must be available 2 days before the finish date, you can enter a negative lead-time offset (2-).
