Re-maping from one sheet to another

I have searched for this to no avail. Seems it would have been asked a few times but anyway here goes.

I have Spreadsheet 1 (snap1.jpg) that is supplied by a supplier.

I have spreadsheet 2 (snap2.jpg) that I use.

I need to move corresponding cell contents from SS to SS and place the data in the correct cells. I call this re-mapping.

The snap shots are only partial there are Br columns to look at.

I would like some sort of script / macro to do this with as updates will be monthly.

Is this an easy thing to do or should I contract it out?

Thank you.
