Required field in one transition tab and in the other

[Mari Car]

Hello, 

I have a transition screen with 1 tab. In this tab I have a field which is required, so when a team member closes an issue, the screen appears and the field has to be filled. Now I want that this field appears in the issue screen belonging to the workflow where the tab is. If I add the field to the screen (view screen scheme) of the issue, I cannot save the issue, because the field is required. 

I want to make this field required only in one tab, in the another it must be read only when filled and only at the end of the workflow.

Do you have a solution? 

Thank you very much and best regards, 

Maria

If you only add it to the VIEW screen, not the create or edit screen there shouldn't be a problem. If you don't have a separate VIEW screen JIRA will use the edit screen and it can't be there.
