Get table data of one doc type & to show it in another doc type

How to get all items details from “Maintenance Schedule Item” table & show data in some other doc type: “Issue”.

@Ram_Gopal_Rao , why not just add a link?

Bcoz we need to add all item details of “Maintenance Schedule Item” into “Issue”

Easiest way to do it is via link.

Using Link I can fetch data of “Maintenance Schedule” into “Issue”, but i’m not able fetch item details of “Maintenance schedule” into “Issue”

I mean to say we can fetch/copy data of other forms into current form. But How can we fetch/copy grid table data of other forms into current form.
