Quota Arrangement
A particular material can be procured from different vendors depending upon the requirement. In this
way, the total requirements of material are distributed to different vendors, i.e., the quota is assigned to
each source of supply is known as a quota arrangement.
Quota rating is used to determine the amount of material that is to be assigned to a particular source or
vendor. The source with the lowest quota rating is called a valid source.
Quota rating = (Quota allocated quantity + Quota Base Quantity)/Quota
Step 1: Change material by selecting quota arrangement and source list in purchasing view.
Quota Arrangement Usage: It determines whether a material in a quota arrangement and which
operation lead to a quota arrangement. For example, you can define quota arrangement to only
purchase order.
Step 2: Create Purchasing info record for material 1 and vendor A and B
Step 3: Create Source list.
Step 4: Create quota arrangement (MEQ1)
I have maintained quota arrangement and maintained quota to different vendors as shown below percentage wise
as per quota rating here.
Step 5: Create PO.
Quota rating for vendor A = (Quota allocated quantity + Quota Base Quantity)/Quota
Quota rating for vendor B = (Quota allocated quantity + Quota Base Quantity)/Quota
Hence, PO & PR placed to the vendor with LOWEST Quota rating.
