It is good u want to go for SAP, u need to decide whether u want to be a functional guy or u want be techanical guy (ABAP programming, etc...).
SAP is good erp which mostly used in the Manufacturing, Hi-Tech, Oil & Gas, Construction, Enery, TRansportation, Retail. SAP is used by big organisation , but now it is gaining ground in SMB market. So if u want to be a functional guy, u need to come from that domain from ur previous work exp or u want to learn from here....
So my personal view, based on the geography u want to get job, ur passion, ur functional knowledge, all the industry are good.
SAP retail is catching up but it has tough figth for the market share from ORacle (Retek application) for Retail indsutry.
Forign language knowledge from the product perpestive has no advantage, but when u work for company, it is useful based on the role u play for requirement gathering, customer support etc...
Also SAP in real estate is catching up fast it has good market in Middle East & aslo in India. Most of the big construction company run the SAP as a ERP system.
Cushman & Wakefiled, which is biggest Real estate company in the world is not a SAP shop, they have build an in house application in .net technogoly.
