Now let's see the concept of request and data groups. Request group and data group are used while defining a responsibility in Oracle apps.
A request group is attached to a responsibility. It defines the concurrent programs you can execute using the responsibility to which this request group is attached.
The following screenshot shows the data and request group attached to a responsibility:
A request group can be queried; to do this, navigate to System Administrator | Security | Responsibility | Request.
A data group is a list of Oracle Applications (Human Resource, Advanced Benefits, Payables, Payroll, and so on) and the Oracle username (HR, AP, AR, and so on) assigned to each application. Each application in a data group must have an Oracle username assigned to it. An application may be listed in a data group only once.
