Key Important Points about Quota Arrangement:
- Quota arrangement usage is mandatory in Purchasing or MRP2 view of Material Master. If it is not maintained, Quota arrangement won’t work during MRP Run and system will give the source of supply based on Source list or PIR.

2. Lot Size must be maintained in MRP1 view of the Material which has Splitting quota active flag.
You can configure the MRP Lot size in the below configuration with SPRO transaction.
IMG Reference – Materials Management – Consumption-Based Planning – Planning – Lot-Size Calculation – Define Lot-Sizing Procedure – MRP Lot Size

3. Source list is not mandatory if you use Quota arrangement. If you maintain Source list with MRP indicator or without MRP indicator or even without Source list, system will split the PR into multiple PRs as per the Quota arrangement data.
3. Purchase info record for the combination of Material and Vendor is mandatory to maintain Quota Arrangement.
