Sy-subrc value is not getting retained

Hi Guys,

My program is calling an instance method in which the sy-subrc value = 4.

But when I come out of the method, back to the calling program, the sy-subrc value is automatically becoming 0.

But based on that value , further processing will be done in the calling program.

That's why I want the unchanged original value.

So is there any way by which we can retain it's value to 4.
