Purchase Grid 
Use
The AFS system makes it possible for you to define application grids so that you can specify conditions and grid values not only for a certain material, but also depending on factors such as the vendor or the purchasing organization. A purchase grid is a subset of a master grid and is always uniquely derived from it. Using purchase grids, specify which of the grid values you defined in the master grid for an AFS material are permitted in Purchasing. You can enter specific SKU numbers, rounding factors, and data for pricing in the grid control data for each purchase grid.

Grid
As a subset of a master grid, the purchase grid contains at most the grid values of that master grid. A purchase grid can be defined for a certain key combination, such as a combination of material and vendor. If purchasing documents correspond to a key combination for which a purchase grid exists, the procurement transaction will be based on this key combination. You can only choose from those grid values permitted for the conditions defined in the purchase grid.
Grid Control Data
For a purchase grid you can enter at SKU level an additional number, a specific rounding factor, and price groups for the grid values.
Additional material number
An additional material number allows you to uniquely identify your material using another number. You can enter this additional number in the
purchasing info record
for the combination of vendor and SKU value. You can, however, also specify this number for a specific key combination in the grid control data of your purchase grid. If you have entered an additional number in both positions, control which of the two numbers will be transferred to purchasing documents using the indicator
Use Add.No in the purchasing info record. If you set the indicator in the purchasing info record, the additional number will be transferred from the purchasing info record. Only if this indicator is not set will the additional material numbers be copied from the grid control data to the purchasing documents.
Rounding factor
In the AFS standard system you can have SKU quantities in purchasing documents always be
rounded
to the multiple of a rounding factor. You can enter the rounding factor in the purchasing info record for the combination of vendor and SKU value. You can, however, also specify this rounding factor for a specific key combination in the grid control data of your purchase grid. If you have entered rounding factors in both positions, control which of the two rounding factors is valid for purchasing documents by setting the indicator
Use ROF in the purchasing info record. If you set the indicator in the purchasing info record, quantities in purchasing documents will always be rounded to a multiple of the rounding factor from the purchasing info record. Only if you do not set this indicator will the rounding be based on the rounding factor from the grid control data.
Assignment of price groups
In the grid control data you specify which grid values of a purchase grid should belong to which price groups. You define price groups in Customizing. You can find more information on working with price groups in the documentation on
Pricing.
You define key combinations for the grid control data in Customizing. You can also specify in the global settings in Customizing for which purchasing documents the
process for grid determination
should be valid.You can find further information in the documentation on
Creating Purchase Grids and Grid Control Data.
