Manual Grid Value Assignment 
Manual Grid Value Assignment
Features
If the component has a different grid than the header material, you must manually assign the grid values of the components to the grid values of the header material in the bill of material.
You carry out the assignment of the grid values of a component to the grid values of a header material in a grid that contains the combination of all grid values of the component and the header material. Then you manually assign the consumption quantities for each individual grid value of the component to the grid values of the header material. These may differ from each other (see
Deviation Quantities and Zero Quantities).When exploding a bill of material during MRP, the system uses the consumption quantities entered here per grid value for the components.
For the winter season you plan the production of a ski jacket in sizes 6, 8, 10, 12 and 14 and with the colors black, white and red. You procure the fabric for this jacket from an external vendor. During the production, the cutting of the fabric is one operation and the sewing another.
During the sewing procedure, a zipper in the corresponding color should be sewn in each jacket. The ski jacket in size 6 gets a zipper in size 44. The zippers in sizes 46, 48 and 50 are used for the larger jackets.
For the ski jacket you stored a two-dimensional grid with the dimensions size and color. The grid of the zipper is one-dimensional and contains the specific sizes of the zipper. The system creates a grid in which you can see the colors and sizes of the ski jacket on the one side and on the other side, you can see the sizes of the zipper. Here, you enter the consumption quantities for the zipper per size/color of the ski jacket.
If the header material and the component have different grids, you must manually assign the grid values of the header material and the grid values of the component to each other. If that is not the case, the system cannot find the bill of material for the header material during the further logistical process.
