Hi All,

I have the following question:

i have job that contain 4 work flow that run in flow like the following:

WF_1 -> WF_2 -> WF_3  -> WF_4

each work flow contain 10 data flow that run in flow.

i want that each time that the job continue to the next work flow it will check first if the

previous work flow finish correct and only if it's finish ok it's start the next work flow

and if the previous work flow had problem it will stop the job and send mail of failure

how can i do this?
