ff-depends on link

[Mary Wilson]

when linking JIRA issues, there are the following link types.  I can't find any documentation on these!  What do they mean?  What are they used for? 

• FF-depends on
• is FF-depended by
• FS-depends on
• is FS-depended by
• SF-depends on
• is SF-depended by
• SS-depends on
• is SS-depended by

In particular,

    1. Finish-to-Start: A depends B onend => A[FS]B = B can't start before A is finished
    2. Finish-to-Finish: A precedes B onend => A[FF]B = B can't finish before A is finished
    3. Start-to-Start: A depends B onstart => B[SS]A = A can't start before B starts
    4. Start-to-Finish: A precedes B onend => A[SF]B = B can't finish before A starts

That is something set up by your administrators for your JIRA.  You'll need to ask them why they've set them up like that and what they mean.

[Mary Wilson]

Ok, well, that's even more perplexing!!! I am the administrator! I have no clue where they came from, or even why they are there. I was caught off guard when a user asked what they were for.

Well, they could have been added by a plugin. Possibly one of the reporting plugins that relies on links (Gantt chart? There are several of those, but I've only really used one, and it didn't do it)?

I have those too.. and I am our system administrator. @Mary Wilson we should compare plugins and gadgets!

Sure @Lacey McDonnell. Shoot me an email (mwilson2@netjets.com).

[Nic Brough -Adaptavist-]

Ta, that answers which addon it was.

This is coming back to me now. I don't have the Gantt add on, but remember asking Atlassian about this. It could have been installed at one time and the link types will stick around.
