On the "Key Field Definitions" tab of a data feed, when trying to configure the key fields for the "Installed Technologies" application, the following message is displayed:
"Keys are not configurable for this module."
Since the "Installed Technologies" application is a leveled application, this adds significant amounts of complexity when targeting this application with a data feed.
Therefore the decision was made to simply this by flattening the view inside the Data Map tab and automatically including the keys for the Installed Technologies application.
The key inclusion is done behind the scenes so you won't see anything in the Key Fields tab for this application. For the flattening of the fields, you will see the fields for every level in the same list when you expand a cross-reference field to the Installed Technologies application.
Important Note:This only works when the Technologies application is referenced as a cross-reference field in another application.
Example: The Hardware application is an example of an application that has a cross-reference to the Installed Technologies application.
Limitations: The Installed Technologies application cannot be specified as the target application in the data feed configuration. The UI will let you do this but the Data Feed job will fail when run. This is a known limitation due to the special processing that occurs to build the keys automatically behind the scenes.
