11-14 Oracle Fusion Middleware Developers Guide for Oracle Data Integrator ■ Mappings that contain reference source columns cannot be mapped on the target. ■ A mandatory column should be mapped. ■ A mapping mapped in one dataset must be mapped in all other datasets.

5. Check the Update boxes if you want the mapping to be executed in Insert or

Update operations. You can also check the UD1 to UD10 boxes to enable KM-specific options on columns. These options are optional, and must be used if the Knowledge Module documentation indicates it. Otherwise, they are ignored.

6. Check Active Mapping if you want this mapping to be used for the execution of

the interface. Note that if you enter a mapping text in a disabled mapping, this mapping will automatically be enabled.

11.3.6 Define the Interface Flow

In the Flow tab, you define the loading and integration strategies for mapped data. Oracle Data Integrator automatically computes the flow depending on the configuration in the interfaces diagram. It proposes default KMs for the data flow. The Flow tab enables you to view the data flow and select the KMs used to load and integrate data. In the flow, the following items appear: ■ Source Sets : Source Datastores that are within the same dataset, located on the same physical data server and which are joined with Joins located on the Source are grouped in a single source set in the flow diagram. A source set represents a group of datastores that can be extracted at the same time. ■ DataSets : Datasets appear as yellow boxes in the Staging Area. ■ Staging Area : It appears as a box that includes the different datasets, the target if located on the same data server, and possibly some of the sources if located on the same data server. ■ Target : It appears as a separate box if it is located in a different schema from the staging area If the Staging Area Different from Target option is selected. You use the following KMs in the flow: ■ LKM : They define how data is moved. One LKM is selected for each Source Set for moving data from the sources to the staging area. It can be also selected to move data from the Staging Area - when different from the Target - to the Target, when a single technology IKM is selected for the Staging Area. ■ IKM : They define how data is integrated into the target. One IKM is typically selected on the Target. When the staging area is different from the target, the selected IKM can be a multi-technology IKM that moves and integrates data from the Staging Area into the Target. Tip: Before proceeding, you can check the consistency and errors in your diagram by clicking the Display Interface Errors Report in the Source Diagram Toolbar. This report will show you errors that may exist in your interface such as mappings incorrectly located. At this stage, you may receive some errors because the Knowledge Modules are not selected yet for this interface.
