After you have created an alias set (as described in Creating Alias Sets), you can add bindings to it. Bindings specify the columns in the data source that hold alias information for a particular alias set.
In this procedure, you create the bindings manually. You can also create bindings automatically, by inspection. See Creating Bindings By Inspection for an Alias Set.
To create bindings manually for an alias set:
Open the Alias Set Manager (Tools, then Alias Set Manager).
Before you can add bindings to an alias, you must have created an alias set, as described in Creating Alias Sets. If you have created an alias set, proceed to step 2.
In the Alias sets list box, select the alias set for which you want to add bindings.
To the right of the Bindings list box, click the Create a binding button to display the Create Binding dialog box.
The Create Binding dialog box includes the following sections:
The Binding source tree, which displays all items in the metadata tree that can have an alias binding associated with them.
The Binding expression text box, where the binding expression is entered.
In the Binding source tree, select a metadata element for which you want to associate an alias binding.
In the source tree under the Binding expression text box, navigate to the column that you want to use to generate a binding expression.
Double-click the column name to add the binding expression to the text column.
Use the source tree below the Binding expression text box to generate a binding expression for the metadata object that you selected in the “Binding source” tree. Alternatively, you can enter an expression in this text box.
The expression you created is displayed in the Bindings section of the Alias Set Manager in the following format:
Under Dimension element, the metadata element that you are associating with an alias is displayed.
Under Binding, the source element on which you are basing the alias is displayed.
Repeat step 3 through step 7 for all bindings that you want to create for the selected alias set.
When you have created all bindings for an alias set, click OK to exit the Alias Set Manager.
