To create cross references for my Luminate CRM to Luminate Online I am going through the steps below. I have so many cross references it's hard to find previously created cross references.
Go to "Data Management" > "Luminate Configuration" > "Cross References".
Click on the "Cross References" button.
Find and "Configure" the needed cross reference type.
Click on the "- Cross References -"
This newer view of the cross reference can be useful for a number of this, for example, easily viewing all of the objects that need a cross reference. However, for now their is no search on that page. For searching purposes, you can use the old cross reference page, steps are listed below. Note that the exact same cross references will be available in both pages; only the layout is different not the cross references in the layouts.
Go to "Data Management" > "Import / Export" > "Cross Reference Types".
Find and click on the name of the needed cross reference type.
