transfer values between different backend ABAP jobs.

Hi expert,

my scenario is : I run a ABAP program Z1 on backend, after multiple hours , it is still running. I want to launch another backend abap program 'Z2' to stop 'Z1'. in program 'Z1', I can get its jobname and jobcount, I want to tranfer these values to program 'Z2'. I figure out following methods from forum.

1. import/export to memory, this is effective for same session.

2. set/get method. they are effective for sam e user, but I don't know if those backend job 'Z1'/'Z2' are belong to this case?

3. import/export to database, I think this is the secure method here.

please give me some suggestion here?

Many Thanks,

Bo
