Request delivery schedule with fixed total delivery qty updated by MRP

Question

Hi Gurus,
Please help on this issue. The issue is since in the "direct Purchase order", the delivery date is fixed & not updated by MRP, seems only delvery schedule line in Scheduling Agreement can be updated by MRP.
Below is the requirement:
1) Use appropriate Purchase Document (like Scheduling Agreement) for subcontracting the in-house production parts when capacity is insufficient, so that delivery schedule qty can be updated by MRP.
2) The Purchase Document will covered partially the requirements of the in-house production parts, the qty covered should be the same as total open qty in the Pur Doc to be delivered (if it's Sch. Agrmnt, should be Target Qty)
3) During MRP run, source of supply should be assigned to the Purchase Doc iteam firstly, afterward assigned to planned order
Thanks a lot!

Hi,
For all of your queries;
ME01 - Maintain Source List for the materials
Here maintain, Vendor, Plant, Purchase Org, most important input Scheduling Agreement No  in Agreement column and  in "MRP" column, use "2" i.e. Record relevant to MRP. Sched. lines generated automatically
Now run MRP and observe the result, it will consider Scheduling Agreement in MRP.
