How to make a field required on condition

[PSPRAVIN]

Below are the fields I have:
#1: Custom single dropdown field (Priority) with values Low, medium, High
#2: Custom single dropdown field (project phase) with values - Production, AssemblyTest, Testing
#3: Custom multiline text field (Alternate Procedure description)
#4: Custom issue type (Defect)
#5: Defect has status of - New, In development, Development complete, System Test, in production

For any Defect that is "Development complete", where the Project Phase = Production and a Priority = Medium, make the "alternative procedure description" field required.

Please suggest how to achieve this ?

Hi @PSPRAVIN

If you have scriptrunner plugin, this is achievable with the behaviours -> https://scriptrunner.adaptavist.com/4.3.0/jira/behaviours-overview.html + You would have to write a groovy script for this
