I have a custom field named 'MoA Signed Date', and I also have 2 issuetypes.
Issuetype A and Issuetype B.

Issuetype A will be linked (using Relates to) with Issuetype B.
When submitting status on Issuetype A, it will copy a customfield (MoA Signed Date) to the Issuetype B that only has OPEN status.
How do I do that? Please Help
Any advice will be appreciated
