Symptoms:
Some users might encounter the following error while trying to run API queries in Web TimeSheet test interface. The issue might be caused if the user running the query do not have Can view All system data permissions enabled in the profile.

"Permission denied by security module, not permitted to load entity of type Replicon.TimeSheet.Schema.ReportPeriod+Entity"

Resolution:
Enable Can view All system data for the user who is facing the error. This permission can be found under Administration > Permissions > Permission Profile > Integration section. The permission is not enabled by default as per the existing security model. If you are unable to find this permission in the instance, please contact Replicon Support to enable the permissions for this  particular SaaS instance. After Support has enabled the permission, the option should be available under Permissions and can be enabled for the users.
