what to choose between MM/SD / GDM...?

Hi ALL,

I have got experience in PP-PI AND QM module of around one and half years.Now there is a requirement in which i need to choose between Materials Management/ Sales and distribution and Global data Management.The project in which i will be asked to work has about 60% SD related work and rest 40% consists of all other modules together.

I don't have much idea about these modules. Can anybody plz suggest which is better to chose among these 3 modules taking into consideration the future prospects.

What is the scope of GDM in future and what will be easier for me to grasp MM or SD.

Your views and suggestions regarding are most welcome.

Regards,

Ameya Khanwalkar.
