Is it possible to use dynamic 'with key' conditions of 'READ itab' ??

Hi~

I want to try to set 'with key' conditions dynamically..

READ TABLE itab WITH KEY <...>.

In this <...> phrase, the condition keys could be 2 or 3( don't know at yet this point)

so i want to make it dynamic with importing data.

Is it possible?

Please help me!

thank you in advance~
