Hmmm, well material planner and procurement mainly is to manage between Vendor and Client. Mainly dealing with bidding process, preparing quesionaire to pre-select some of the vendor.
So if you are a fresh grad and if you think u not a very technical person maybe it could suit your needs but after few years you might forget how to design a valve or pipe, your job is mainly preparing documents for vendor to bid and to help client to choose which vendor and the procurement process took quite a lot of details also. Anyway its a challenging job too cos it deal with money hahha..... as for future palnner u can become Contract manager cos you will deal with a lot of contract between client and vendor.

But it just base on my own opinion just as a reference, the choice is still in your hand.
