How To: Share Business Analyst Online and Community Analyst sites with other members of an ArcGIS Online organization
Sites that have been created in Esri Business Analyst Online or Esri Community Analyst can be shared with other members of an ArcGIS Online organization. This is accomplished by sharing the site(s) through a web map in ArcGIS Online and adding the web map to a group. The group and its contents can then be accessed by group members from Business Analyst Online or Community Analyst.
Sign in to ArcGIS.com with the same login used for Business Analyst Online or Community Analyst.
Click on Groups at the top of the page and click Create a Group.
Give the group a name and tags, select an appropriate Status, and then save the group.
Open the group and click Invite Users. Use the dialog box to invite any organization members with whom the sites should be shared. For information about inviting and managing group members see the following web help topic: Own groups
