We support a separation of duties policy between users who create and approve merge requests.
Our criteria for the separation of duties is as follows:
- [A merge request author is **not** allowed to approve their merge request](../../project/merge_requests/approvals/settings.md#prevent-approval-by-author)
- [A merge request committer is **not** allowed to approve a merge request they have added commits to](../../project/merge_requests/approvals/settings.md#prevent-approvals-by-users-who-add-commits)
- [The minimum number of approvals required to merge a merge request is **at least** two](../../project/merge_requests/approvals/rules.md)
> - [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/213364) in GitLab 13.3.
> - Chain of Custody reports sent using email [introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/342594) in GitLab 15.3 with a flag named `async_chain_of_custody_report`. Disabled by default.
FLAG:
On self-managed GitLab, by default sending Chain of Custody reports through email is not available. To make it available, ask an administrator to [enable the feature flag](../../../administration/feature_flags.md) named `async_chain_of_custody_report`. On GitLab.com, this feature is not available.
1. On the left sidebar, select **Security & Compliance > Compliance report**.
1. At the top of the compliance report, to the right of **List of all merge commits**, select the down arrow (**{chevron-lg-down}**).
1. Enter the merge commit SHA, and then select **Export commit custody report**.
SHA and then select **Export commit custody report**.
The Chain of Custody report is either:
- Available for download.
- Sent through email. Requires GitLab 15.3 and later with `async_chain_of_custody_report` feature flag enabled.
- Using a direct link: `https://gitlab.com/groups/<group-name>/-/security/merge_commit_reports.csv?commit_sha={optional_commit_sha}`, passing in an optional value to the
