Set Operations

You can use set operations to relate two sets of objects to each other. You can use the resulting set for output, as a reporting set for further selections, or for further set operations.

You are working with object selection.

You can show the Set operations tab page for the set operations. The set operations process the sets from the Object set A and Object set B fields, and write the result to the Resulting set field.

You can perform one of the following set operations:

• Create intersection

• Create union

• Set A minus set B

• Set B minus set A

Once you have executed a set operation, you have the following options:

• If you want to use the resulting set for output, you must copy it to the Hit list.

• If you want to use the resulting set as a reporting set for further selections, you must copy it to the Reporting set.

• If you want to use the resulting set for further set operations, you must copy it to set A or set B.

You want to run a report to determine which employees at your enterprise do not have a temporary residence. You cannot select non-existent data records, so you implement the report according to the following logic:

• First, you select all of the employees at your enterprise and copy this set to Object set A.

• You select all of the employees with a temporary residence and copy them to Object set B.

• Set operation Set A minus set B enables you to subtract all of the persons with a temporary residence from the set of all employees. The resulting set contains all of the persons who do not have a temporary residence.
