MRP- suggesting incorrect quantity

Hi,

Our Forecast for FG item A is 500 CR.

We have run MPS (R3482 - Regeneration mode, with generation type 1 Horizon period 6 months) for FG items. Report correctly suggested 500 CR message as there was no Oh-hand.

But When we ran MRP(R3482 - Regeneration mode, with generation type 4 Horizon period 6 months) for SFG item B which is there in the BOM of FG item A, it is creating WO message for only 10 KG.

There is no On-Hand quantity for Item B.

1 CR of item A needs 50 GM of item B.

Hence, It should suggest 25000 GM that is 25 KG message suggestion.
