extract Context to itab

Hi All,

On my Component Init I have extracted some value from DB table and store in a context,

Inthe program at several place i need to compare the value user give against the table.

Is it best if i loop thourgh the context and read every value or extract it to a internal table and then run the validation.

I dont know how to extract the whole context at once. i only know how to read by index. Please guide me on how i can extract them at once and the loop them....

Thank you.
