Depending which version of ILMT is running, ensure it is running the latest version (9.2.21) as it also comes with the latest software catalog which might already have the signatures for these two components in question. If you can get a hold of software signature tag files from the servers where these components are installed, you could upload them to this thread and I could try to test it in my lab environment.
As suggested before, try searching these components in ILMT portal under the Software Catalog widget (i.e. “IBM Datacap” or “IBM FileNet Content Engine”. It should return a list of matches.
If you are already running the latest version of ILMT and still could not identify these components, then you would have to open up a PMR to address the issue.
