Consider as an example that you want in your data model to retrieve the agency
region, on the fly, from the source system without really saving the region in the
MDM Hub.
Before you begin
- The MDM server is up and running.
- You have already connected to the MDM server from Talend Studio.
- A data model has been already created.
About this task
To define the entity elements to be transformed/enriched by a Process, do the
following:
Procedure
-
In the MDM Repository tree view, expand the
Data Model node and double-click the data model
in which you want to define the elements to be handled by the
Process.
In this example, you want to set a lookup field
Region on the
Agency entity in order for a corresponding
Process to retrieve the agency region from the source system.
-
In the Data Model Entities panel, right-click the
entity from which you want to select the element(s) to be handled by the
Process.
A contextual menu pops up.
-
Select Set Lookup Field to open a dialog box.
-
Click the arrow and select from the list one of the elements pertaining to
the selected entity.
-
Click the
icon in the upper right corner to add the selected element to the
Lookup Fields list.
-
Do the same to add as many elements as necessary to the Lookup
Fields list.
Warning: Only listed elements will be transformed/enriched on
the fly by the Process. If this Process modifies anything else in the
XML record, these modifications will be ignored at the entity level
because the Process will send only the specified elements and not all
the XML record.
-
Click OK to close the dialog box.
The defined look up field(s) will be displayed under the
Annotations node corresponding to the entity
selected in the Data Model Entities panel.
