Job steps

Hi Gurus

I have some question that I can not resolve, maybe you can help me.

I have to create several job steps in a background job.

Let say:

1 step program ztest01.

2 step program ztest02.

I want my 2nd step (ztest02) always executed regardless what happend in 1 step (ztest01).

My problem is it happened that a message error of type 'E' in my 1st step (ztest01) has been triggered resulting my 2nst step never executed. How to resolve that?

Thank you
