MRP Planned Purchase orders - min purchase quantity - Safety stock

Hi,

We have the following situation for a purchase item.

Safety stock 50

Min Purchase order quantity 500

Purchase Multiple 100

We have 0 stock, after the mrp run we suggest that AX will creaties a Planned Purchase order of 500, instead the mrp creaties a Planned Purchase order of 50.

They want to create a situation that when the stock goes below 50, a planned purchase order is created of 500.

Kind Regards,

JB
