how to compare a custom field that is shared between two projects?

[Vijay Sv]

Is there a way to compare a custom field that is shared between two projects and link the issues if the shared custom field has the same value. 

or maybe using Groovy.

What is the type of custom field?

[Vijay Sv]

it's a nfeed custom that is shared between two projects and when an issue in both projects has the same custom field value, those issues needs be linked.

With scriptrunner you can compare if field value are the same

Yea, but i need to compare the value of that custom between just 2 projects and link them if the value of the custom field is the same in both the [rojects.

Hum, i'm not sure its possible since its the same field (and name) but in different project. I will try a subfilter but i'm sure it won't work
