You can use the getcontentdetailsbyUUID(uuid) custom function, this is not part of the out-of-the-box Appian functions, you have to deploy the plug-in. The plug-in is available for download here in Forum under Components - Expression Functions - View All Expression Functions - Content Details by UUID.

In the SOURCE environment (where the application is being taken from) Place the downloaded JAR (find it attached for your convenience) under <APPIAN_HOME>\\_admin\\plugins, wait for it to be installed automatically (takes around 1 mn) which can be confirmed in the application server log:

16:17:18,607 INFO [STDOUT] 2011-11-28 16:17:18,592 [Plugin Hot Deploy] INFO com.appiancorp.plugins.LoggingPluginEventListener - Successfully installed Plug-in
'Content Information Retriever' (uuidinformationretriever) version 1.0.0.

16:17:18,624 INFO [STDOUT] 2011-11-28 16:17:18,624 [Plugin Hot Deploy] INFO com.appiancorp.plugins.LoggingPluginEventListener - Successfully installed Modul
e 'GetContentDetailsByUUID Function' (uuidinformationretriever:getContentDetailsByUUID) version 1.0.0


Once installed, you can now create a rule that receives a single input, let's call it uuid of type text and the defintion of your rule will be:

=getcontentdetailsbyUUID(ri!uuid)

When testing the rule just copy and past the missing content UUID, for instance, for this error you describe:

_a-0000d6e1-ec1d-8000-0d1b-680000680000_16704

The expression will tell you what document, rule, constant this is.
