Hi @Anantha27 ,

If priority is Critical/High in Problem, You want to insert a new record in Problem Task:

You have 2 ways to approach this:

1) Flow Designer: If your condition Priority is Critical OR High then you can create a Problem Task with default value. Without any scripting. If you want some field values then configure as per requirement.

2) Through After BR on Insert OR update: You can use script for this to copy fields values of existing problem table to Problem task table.

Use either approach as per your requirement.
