Question regarding Stored Proc

Hi,

I am new to this. I have a SQL Service broker and there is a service  S1 

Now I have 2 SQL Agent jobs  each job calls the same service but calls different procedure P1 in job1 , P2 in job 2 via same services  . aim is to run 2 jobs in parallel.

Is there any way that I can find out which stored procedure is called via service in both jobs  . actually in job1 , I need to execute  a step after procedure P1 processing has finished

and similarly in job2, I need to execute a step ,after procedure P2 processing has finished

so how to find if P1/P2 processing has finished 

Thanks in advance
