MRP Type V1 collecting requirments problem !!!

Dear Gurus,

I'm planning one of my components in the BOM with MRP Type V1: Manual reorder point with external requirments and lot size EX: lot for lot

I'm making the MRP type setting to take the requirments in the total horizon, and to consider order reservations.

Here is what happend with me:

- I made an order starting after 10 days which made a reservation

- I made another order starting after 15 days which made another reservation

- After running the MRP, it created ONLY ONE planned order covering both requirments !!!!

What I thought is that it should create two planned orders covering each requirment

Is the system's behvaiour normal or not, and what to be done to get my requirment done ?

Regards,

MaX
