How to get the material requirement as per the sales forecast?

Hi All;

Ours is a manufacturing firm. We are not able to get the material requirement as per the sales forecast.

We enter the sales forecast for the manufactured parts customer wise

The we run the MRP the system suggests with Unfirmed jobs for the forecasted items

We need to firm the jobs and then run the ERP which is not practically correct.

Kindly suggest me how the issue could be sorted out.

Regards
