Since rights restriction not only refers to functions but data as well, CARL Source allows you to limit access to certain data according to groups of users.

This function also makes it possible to define the default values of a certain number of fields for a group of users, thus avoiding repetitive entries when a value is almost always constant.

The principle is as follows:

1. For each function where this is necessary, you define which attribute is used as the restriction criterion; see Data access criteria. A default value may be assigned to this attribute.
   
   
2. You then create a data access group that corresponds to possible actions (View, Create, Delete, Change) for a set of values for these criteria.
   
   
3. Lastly, you assign this group to users who must only access a portion of the data for reading and/or writing; see User [General].

 

Example

You wish to create a group of users with restricted work order rights:

• They must only be able to create "Repair" or "Adjustment" work orders. Most of the time, they create “Repair” work orders. They may, however, view all work orders.
• They may only view low-priority WRs.

 

1. Create the following access restriction criteria:
   • [Work order types] function, the "Code" criterion.
   • [WR management] function, the "workPriority" criterion (Priority).
     
     
2. Create the CORRECTIVE group, Corrective and not priority:
   • [Work order types] function:
     • Assign the default value “REPAIR” for this criterion,
     • Uncheck the “Access to all values” box,
     • Delete work order types other than REPAIRand ADJUSTMENT.
       
       
   • [WR management] function:
     • Uncheck the “Access to all values” box
     • Select all priorities -> they are accessible for viewing by default,
     • Check the “View” box for low priorities only.
       
       
3. Assign the CORRECTIVE group to the users for whom this restriction applies.
