When using Group Push functionality, there are a host of requirements and considerations to keep in mind:

• Using the same Okta group for assignments and for group push is not supported. To maintain consistent group membership between Okta and the downstream app, you need to create a separate group that is configured to push groups to the target app.
• Full list of group push prerequisites: Group Push Prerequisites
• Group Push Operations
• Users shown as inactive in Okta are not pushed to the downstream app. Inactive users must be reactivated and then the group re-pushed. If the inactive user is part of more than one group, they must be re-pushed to all groups in which they are members.
• Making changes from the target app causes a misalignment with Okta and creates a number of problems. Some can be diagnosed through the Errors page, while others may not.
• Troubleshooting Group Push

Finally, if these push groups are using Group Linking functionality, see below

Manage Group Linking

All group push operations can be completed from the Admin UI, with no need to do any part of the operation via script or API call.

Please see:

• Group Push lets you push existing Okta groups and their memberships to provisioning-enabled, third-party applications. These memberships are then sourced by Okta.
• Group Push adds groups to third-party apps, but it does not create groups in Okta. Pushed groups are managed from Okta. Making changes to the group in the target app causes synchronization issues with Okta.

With that being said, the purpose of group push is to push a group and its memberships into the target app. It will push an empty group to the target app, but be warned, it is not recommended (see above) to modify group memberships from within the target app.

Finally, Do you see an error message or more detailed description of the error? Many times you will be provided with an error on the "Group Push" or "Tasks" page that can help guide you to a solution.

Thanks!
