Thank you Sachin for the quick response but I am attempting to create a duplicate of the OOB related list called "Affected by Task" which lists the all the tasks associated with Affected CIs which reside in "task_ci" table. 

 A result wherein the tasks from the table are by default filtered based on the parent record in this case "Testing CR" , see screenshot:

Affected by Task [OOB Related List]

Custom Related List - Affected CIs (Related tasks)

 In this related list , I created it displays all the tasks in the "task_ci" table and is not filtering by default on the parent record in this case "Testing CR"

Any suggestions on how I can get a related list that mimics the OOB related list called "Affected by Task". Thank you again for your help , much appreciated!!
