Accessing Matrix Maintenance
On the Organizational Management screen, choose
Simple Maintenance 
Matrix Change 
or
Display . The
Access Matrix Organization dialog box appears.
This screen enables you to access matrix maintenance in one of three ways:
-
Choose a predefined matrix type
-
Specify a matrix view as a variant
-
Determine a matrix view using standard selection
If you use the first method, you choose the matrix type that you require from the predefined matrix types and then start matrix processing. You choose only the root object for all horizontal and vertical objects. The required relationship between the dimensions is predetermined by your choice of matrix type, as are the object types and the evaluation path of both dimensions.
You can choose standard matrix types or define them yourself in Customizing. If you define matrix types, you can use object types and objects that exist for this purpose. You can also set up new object types, objects, and relationships in Customizing.
If you use the second method, you specify the name of the matrix view with which you previously worked, and which you then saved as a variant. This determines the root object for all horizontal and vertical objects, as well as the required matrix relationship. This facilitates direct access of matrix processing. You might want to use a variant if, for example, you frequently work with the same matrix view.
If you use the third method, you can determine the required matrix view yourself. You access a selection screen in which you enter the required root object type, and the root object, for both dimensions, as well as the relationship between the dimensions. You can also specify an evaluation path for each dimension, which enables you to determine the objects that can be displayed in the matrix and hierarchy view.
