Query QM or RDNG artifacts of a specific type created within past time range

It appears that you can query for QM/RDNG to return the list of artifacts for a specific user based on a date range but note that the results for that query may change depending on when the artifact was last modified.  I was told this is the case even if you query against the data warehouse.

For RNDG, it also depends on whether config mgmt is enabled for the project.  If enabled then only LQE can be used; it would show the last modification of all the versions that are mapped to configurations.  If not enabled then both LQE and DW would only contain the very latest state of the artifact.

For QM, it appears that you can only query against a specific artifact type as opposed to having the query return all artifacts of all types.  In addition, QM seems to operate on the latest modified date much like RDNG.

Yes, there is a way to programmatically create and run such queries using the Reportable REST API.  I've provided the links below.
