MRP Run with Quota Arrangement

Hi Experts,

We have below scenario,

Supplying plant/Manufacturing- 1000

Supplying/demanding plant- 1100

Supplying/demanding plant- 1200

Supplying/demanding plant- 1300

Supplying/demanding plant- 1400

1) Our 1st requirement is that, if we have planned independent requirement and sales order on say plant 1100 or 1200 or 1300 or 1400, and when we run MRP for these plant, for say material AX000

Then system should create STPO and check stock at plant 1100 and if stock fall short then system should create planned order in plant 1000,

Example - AX000 Stock, PIR detial,

Below should be result after MRP Run,

2) Our 2nd requirement is, if we have planned independent requirement and sales order on say plant 1100 or 1200 or 1300 or 1400, and when we run MRP for these plant, for say material AX000

Then system should create STPO at 1400 and check stock at plant 1300 then at 1200 and then at 1100, if stock fall short then system should check stock and create planned order in plant 1000,

Example - AX000 Stock, PIR detail,

Below should be result after MRP Run,

We tried checking 1st scenario with Quota arrangement, its kind of working but the requirement is directly getting divided between both plant, no matter whats the stock, that is not right for us,

checked by maintaining quota 100-100,0-0, 70-30, in earlier 2 case its getting divided 50-50 and in 3rd case as per the ratio,

Please suggest how can we achieve our requirement, is there any SAP note available or any enchantment available for the same?

Thanks,
