Parent->child->grand children- displaying on boards and reporting

[corky cork]

how do I report on: 

Parent tickets-> child tickets->grandchildren of child tickets in different projects.

There are hundreds of issues. 

Parent and child tickets are in one project. Grandchildren tickets are in other projects.

I have 3 queries: 1. Parents 2. children 3. grandchildren but how do I link the children with the grand children and then link the parents with the children so I can see:

1. Parent ticket column 1 . Children tickets in column 2 . 3. grand children tickets in column 3 which relate to the children tickets

Each child ticket can have many grandchildren

Context of data: Parent: Instructional document

Child: tickets representing each task of the instructional document

Grand children: dev tickets relating to each child task

thanks

Hello @corky cork ,

Welcome to Community! :)

Which type of linking you use among all parents-children? If this is "Parent Link", which comes from "Plans"(Advanced Roadmaps), you can use the functionality of the plugin. 

Can this be a solution for you?
