Thanks, unfortunately I can't find Smart Management in TADDM - we are importing all the separate applications that make up RHEL so would need to know which we need to look for. (If that makes sense?)
So from this description it sounds like TADDM isn't detecting/reporting on the existence of Smart Management. You could try reaching out to TADDM experts to discuss whether anything can be done about that.
If the source data doesn't identify Smart Management as being installed, then FlexNet itself won't have any evidence to detect it either. If TADDM can be configured to be able to gather details showing Smart Management as installed that FlexNet imports as installer evidence, then you will be able to configure an application recognition rule in FlexNet to recognize it (if an appropriate rule does not already exist).
