If you refer to ticket IDs under the PRs then the option "Map commit to Pull Requests Issues" is used for the PM integration to fetch it. There are two ways to map Git commits to PM issues:
- The “normal” way is by including the PM issue ID in the commit message, eg. ABC-1234.
- Some teams use a different approach, where they have the ID in the Git branch name instead, eg. abc-1234-fix-the-broken-things.
From the user’s point of view, this means that you can ignore “Map commit to PR issues” if
- you use “smart commits”, ie. PM issue ID in the commit message, or
- you don’t use the branch/PR scheme described above.
