Can anyone tell me that how to fix this issues! I have one job that export the data to warehouse and never finishes up at all!!
You have to check what is going on.
Try to execute this job by steps and see what happens.
What is the job anyway? Is it DTS package or SQL Statement? Try to execute it task by task if it is a package. Try to export just the minimal amount of sample data to see how long does it take. Log messages at every step of the package.
