Error 00008: You do not have permissions of Field

Cause 1

There are fields in the drill-down hierarchies of the Jobs assigned to the mobile user that they do not have access to in their security profile. If the field is a relationship field, they'll also need object level access to the parent object in that relationship.

Solution

1. Go the Setup > Objects.
2. Click on the object name that the field belongs to.
3. Click on the field.
4. Click on Set Field-Level Security.
5. 
6. Ensure the checkbox "visible" next to the user profile is marked as below.

Cause 2

The Standard Event and Task object uses a polymorphic lookup field 'Who' which can be related to multiple objects at one time. When these objects are used on Drill Down Hierarchy, no records will be visible.

Note: TaroWorks does not support polymorphic lookup fields found in some standard objects such as Task and Event.
