Hi Bilal,
Check if you are using the same parameters in the MRP run.
Note that maybe you are running the MRP with different parameters (to create planned orders in one case and purchase requisitions in the other case). Now if you are running the MRP with the same parameters for both materials, follow the response sent by the expert Caetano.
Anyway, try to run MD02 with the parameters

And check MD04...
