Make "Description" required field in 1 screen on certain issue types

[Deleted user]

Hi Community,

Is there a way to make the "Description" field mandatory on all issue types except "sub tasks"? Also, is there a way to make this the case only for the screen that I use?

Currently, I can see how to make the "Description" field required, but it affects all screens and all issue types.

Many thanks,

Toni

The colleague helped: 
the documentation indicates the use  of JFieldChanges [] : https://confluence.cprime.io/display/SIL/getFieldChanges 

but actually: 

string k="TEST-5";
string[] field_history;
field_history = getFieldChanges(k, "duedate");
runnerLog(field_history);
