ABAP Descriptor Classes for Dynamic Local Declarations

Hi Friednds,

I need to create Local Internal table in my program. I had initially used cl_alv_table_create=>create_dynamic_table for my table creation. But due to a limitation I canot use this.

Someone told me I can use Descriptor Classes for this.

But I dont know how to use it to create the local table..

I am having all the fieldnames and their Types at present in my program. How do I call these classes to crete my Local Tables and Structures.
