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.

Remember this needs to be executed in the environment WHERE YOU CREATED the app NOT where you are importing it.

Many thanks Eduardo. Following your instructions now. Thanks again.

if there there any missing dependencies,you will get this exception.
can you check missing dependencies once in application
