Hi Jayashree,
Have you checked out the DQ+ User Guide (select Home, then Help within DQ+)?
Runtime Properties
Runtime Properties can be created by selecting a Data Store and mapping a field containing names to a field containing values. The property can then be referenced via the name field throughout the Analysis, using the RUNTIME() function.
I've also attached a screenshot of the RUNTIME function description.
Let me know if this helps.
Jeff
