How can I download forecast data?

I am relatively new to SAP and I am trying to figure out an easier way to download the forecast requirements (generated elsewhere by other users) for a few hundred part numbers for the next 18 months. Currently, I go into MD62 and copy 30 materials at a time into my list and then copy as many columns as possible from SAP and paste into Excel. This is VERY time consuming and I'm sure there is a better way, I just don't know it.

Ultimately I want a forecast by period something roughly along these lines:

Thank you.
