You will need the Reporting and People Mass Change permissions, plus Limited Write Groups for the group, to perform this action. The change reaches only the people your query returns, and if you have campus overrides, only people at campuses where People Mass Change holds.
Churches often need a way to add several people to a particular group, and One Church Software provides an easy and efficient way to do so.
Go to Reporting in the left-hand navigation menu, and click on Query Builder; make sure you are using the People data source.
Once there, you can choose a variety of Filters, on the left of the page, to extrapolate data and then adjust the Query, located in the middle, accordingly. Columns, located on the right, can also be added, deleted, and replaced, but this won't impact the people who are added to a group.
For more on filters and columns, see How do I add filters? and How do I change the columns in the results?
Once you are satisfied with the filters, query, and columns, scroll down the page, click Run Query, and then select the Bulk Actions button. From there, you will see in the list an option to Mass change.
Preparing to Do a Mass Change
As shown in the pop up, click on Perform an action.
On the sidebar, select Add To Group.
Type and then select the appropriate group you wish to add people to.
A pop up displays that lets you choose the member type, whether they should be admins, and the date the people should be added to the group. Once you are satisfied, click Done.
A series of pop ups will display, asking you to approve the mass change; click on Update X Records on the first pop up, and then enter the number of records being changed as shown in the box of the second pop up and click Continue.
You have now done a mass change to add people to a specific group. There is no campus rule on group membership, so people are added whatever campus they attend.
