[Mahesh Jillella]

Hi All,

Is there any relation between  following tables  , If exist what type of relationship is that 

1. Incident

2.problem and

3.change management tables.

Hi,

All these tables Incident, Problem, Change are extended from Task table in ServiceNow. Task is the parent table in ServiceNow, so most of the fields on this forms are derived from the parent Task table itself.

Also, you can create a Problem or Change from Incident, or, Change from Problem, or can create an Incident from Change request in cases where it is required.

Hope this helps.
Mark helpful or correct based on impact.

Thanks.
