How to create a report in servicenow using two different tables

[GaneshUrs]

I have a table named "problem" and another table named "problem sla" where we get different details from the problem records. I believe it is possible to create a report using dataset with graphical view. However, my requirement is to create a List report using or merging both these tables which can provide all relevant details.

Hi @GaneshUrs ,

i wouldn’t recommend to build a new database view, but indtil utilize the existing task_sla and ensure to only look at problem. The reason that this can be utilized is, that problem is extending the task tabel.
