timing problem can i run online report in background after user give values

hi,

can i run online report in background after user gives values and executes it. its a dialog program.i am having the problem because, the program takes lot of time to execute records in internal table, some times it may take 50 min, so currently time out occurs and system times out in the middle of process , processing some and not processing some. is their anything like job_open etc to do it.

thanks,
