Background job reads old variant

Dear All,

I have one background job which runs ABAP program with a given variant.

However, when I change the parameters for that variant the bacground

job runs the ABAP program with variant old values.

So whenever I change variant parameters I'm forced to stop

background job and schedule it from start.

Is it possible to have background job that runs ABAP program and

reads always updated values for a given variant?

Best regards,

Karl
