Input parameter for F.M or class to create dynamic internal table

Hi Experts,

I have to develop a class or a function module which should have a parameter to passing any kind of internal table data.

This class or F.M will be used in various programs which pass different internal tables.

I am thinking to create a dynamic internal table in my program but how to get data from calling prorgam in my F.M or class?

How should i define the parameter ?

Please let me know how to go about it

Thanks
