Set Date based on another number field via automation in Jira

[Harsh]

Hi All,

I would like to know if it is possible to set date based on the value of another numeric field via Automation. I remember I have read some where it is possible but can't find the thread. Can some one help me with this. I want the following:

Start Date (Date field), Due date (Date Field), Planned Days (numeric field)

I want to populate Due date = Start Date + Planned Days, via automation.

Is this possible.

Thanks is advance!

Found it. 

For others to figure it out.

Use the smart value - {{issue.customfield_123.plusDays(issue.customfield_456)}}

Where customfield_123 is START DATE and customfield_456 is Planned Days

Thank you :)
