how to schedule one instance at a time consecutively

Hi Everyone,

We are at BOXIR3.1 SP5 installed in RHEL and business is looking for below mentioned scheduling option for specific webi reports which are complex and having high volume of data.

Lets say the scenario is if the users schedules the specific webi report concurrently, the report should run only at one instance at a time which means the later submitted reports should wait for the first submitted instance to complete.

Please share your thoughts, comments or any suggestions to the above situation.

Thanks,

Karthik
