Hi,
Once you create teams in BPC security, assign some members to that team.
Now, in your EPM addin, by default, the templates are usually stored in the COMPANY folder. While saving the templates, you will see the teams, on the left side, that you have created in BPC admin.
Save the templates in one of these teams.
Please note that you need to be part of the team in order to save the template.
Hope this helps.
