Currently which SAP Functional module is in Boom in the market. Need expert Advice.

Hi Sap Forum,

I am sap crm technical consultant having 6 years of experience and i need to learn a functional module which is good in the market. Can you suggest which is good in the market and which can atleast sustain for 10 years in the market.

I have heard about SAP HANA admin and SAP APO and BPC and EWM. Can experts suggest me which amongst these are good from which i can get good opportunities.

I am also aware about Hybris and Ariba which had a good boom, but not sure about it.

I need to learn one amongst the above 6 modules in sap. Can experts suggest.

Thanks

Mathew
