The source of groups that appear under "Filtered by" in the "Add Modifier" screen is not clear and it does not show the groups that appear under "Manage Recruiting Groups" either.
Successfactors Recruiting Job Requisition
Reproducing the Issue
Navigate to Recruiting >select a pre-approved Job Requisition which has to be approved by the user > click on Add Modifier button to add new modifier/approver to the Route map.
Click on Filtered by -> All groups
You can see that there are groups which do not match the "Manage Recruiting Groups" and even if you add a new group here, it does not reflect in the above dropdown.
Th is because the groups that appear under "Filtered by" in the "Add Modifier" screen appears from the Dynamic groups.
Under (Account Navigation for the user Options) -> Settings -> Groups
(These are the groups that appear under the All groups list)
To add a Dynamic group Under (Account Navigation for the user Options) -> Settings -> Groups -> Create New Group
(Note : Dynamic groups are not recruiting specific and the groups added here will be available for other modules as well)
