Requirements Distribution Ratio 
Requirements Distribution Ratio
Use
You use the lot-sizing procedure after determining a requirements distribution ratio if you want each generated procurement proposal to contain all the grid value characteristics of one or more requirements within a period.
Features
After the determination of a requirements distribution ratio you use the lot-sizing procedure to calculate the percentage ratio between the total requirements quantity of one or more requirements, such as sales orders, and the requirements quantity per grid value within a period. Based on this ratio, the system creates procurement proposals during the MRP. In this case the requirements quantity per procurement proposal depends on the maximum lot size.
You receive two sales orders with a total requirement of 800 polo shirts.
The quantity is distributed across three sizes S, M and L in the color black. You calculate the ratio between the total requirement of all grid values and the total requirements of the individual grid values of both sales orders.
The maximum lot size for a procurement proposal is 100 pieces. In this case this is valid for a planned order. The total requirements quantity of 800 pieces shows you that you require 8 procurement proposals, each with a maximum lot size of 100 pieces.
Based on the determined requirements distribution ratio, the system calculates the required quantity per grid value and creates the planned orders.

Each planned order contains only one category.
The lot-sizing procedure does not consider SKU groups. Special lot-sizing procedures were developed for this (see
SKU Group Procedure 1 and SKU Group Procedure 2).
