Why are the users unable to view records that the Administrator can view?
By default, the data sharing and data viewing options in Zoho CRM account are based on hierarchy. Users at the top level of the organizational hierarchy will have access to all the records, while users in the lower levels of the hierarchy will have access only to the data they own.
For example: The Administrator can access all the records. On the other hand, the manager can access only his records and that of his subordinates. He will not have access to the administrators' records.
The user will be unable to view some records if:
The user is not the Administrator.
The records are not shared by the administrator using the Data Sharing feature.
