Forecast MD61 with PBOM and consume with Service Orders

Hello,

I would like your assistance,

My wish forecast consumption with MD61, I would provide my monthly consumption on PBOM.

SAP will explode PBOM, create purchase requests on childs.

Then I would create orders services indicating the real consumption of childs.

SAP will reduce the estimated versus actual consumption for each month.

This is possible?

Maybe replace Service Orders by Sales Orders, but I must indicate consumption on Childs and not on the PBOM.

Thanks in advance if you can support me.
