Understanding how MRP is calculating Sum Qty Reqd

Get Help & Support
1

Right now, the Sum Reqd Qty calculation seems to be doubling the total # of parts that I need and adding the ROP.

For example, for a specific PN:
I have 0 on hand and need to order the total I need + ROP total, so I expected sum of req’d qty to be :

Qty 1871 = Qty needed for builds (1400) + ROP (471)

However, MRP is calculating as :

Qty 3271 = 2x Qty needed for builds (2x1400) + ROP (471)

Is this happening consistently for every part on MRP or is it only that specific part?
Can you provide us the part number that you’re looking at, or a more recent one that is having the same issue?
