11-10 Oracle Fusion Middleware Developers Guide for Oracle Data Integrator To add a temporary-type source datastore to an interface:

1. In the Designer Navigator, expand the Projects tree and expand the project

containing the interface to be inserted as a source. 2. Select this interface, then drag it into the Source Diagram. The source datastore appears in the diagram.

3. In the Diagram Property tab of the Property Inspector, modify the Alias of the

source datastore. The alias is used to prefix column names. This is an optional step that improves readability of the mapping, joins and filter expressions. 4. If you want this interface to generate a sub-select corresponding to the loading of the temporary datastore, check the Use Temporary Interface as Derived Table Sub-Select box. If this box is not checked, make sure to run the interface loading the temporary datastore before running the current interface. To delete a source datastore from an interface: 1. Right-click the title of the entity representing the source datastore in the Source Diagram.

2. Select Delete.

3. Click OK in the Confirmation dialog.

The source datastore disappears, along with the associated filters and joins. Note that if this source datastore contained columns that were used in mappings, these mappings will be in error. To display the data or the number for rows of a source datastore of an interface: 1. Right-click the title of the entity representing the source datastore in the Source Diagram.

2. Select Number of Lines to display the number of rows in this source datastore or

Display Data to display the source datastore data. A window containing the number or rows or the data of the source datastore appears.

11.3.4.2 Define Lookups

To add a lookup to an interface:

1. From the Source Diagram toolbar menu, select Add a new Lookup. The Lookup

Tables Wizard opens.

2. In the Lookup Table Wizard select your Driving Table from the left pane. Source

datastores for the current diagram appear here. Note that lookups do not appear in the list.

3. From the tree in the Lookup Table pane on the right, do one of the following:

■ From the Datastores tab, select a datastore from a model to use as a lookup table. Note: If the source datastore is journalized, it is possible to use only the journalized data in the interface flow. Check the Journalized Data Only box in the source datastore properties. A Journalizing filter is automatically created in the diagram. See Chapter 7, Working with Changed Data Capture for more information.
