Azure Purview: Missing assets while reading Teradata

Hello,

We're currently testing Azure Purview on a proof of concept and we are facing some strange behavior.
We successful added the new Teradata source and the scan currently retrieves 1,731 assets, however when browsing trough these assets only 1,395 are available.

One tip of what might been going on?
I've already excluded the scan, the assets, re-executed everything but this scenario keeps repeating.

    @Dias, Francisco P - One thing keep in mind is the difference between [Number of Scanned Assets] v.s. [Number of Catalog Items (i.e. Entities)]. If there are instances of resource sets as an outcome of the scan, the latter is likely to be LESS.

    Do you know if some of those assets have been aggregated into a logical resource set?

    For example, these three (3) physical resources:
    • https://myaccount.blob.core.windows.net/mycontainer/weblogs/cy_gb/1004.json
    • https://myaccount.blob.core.windows.net/mycontainer/weblogs/cy_gb/234.json
    • https://myaccount.blob.core.windows.net/mycontainer/weblogs/de_Ch/23434.json

    May materialise as one (1) logical resource within the catalog:
    • https://myaccount.blob.core.windows.net/mycontainer/weblogs/{LOC}/{N}.json

    Therefore in this example:

    • [Number of Scanned Assets] = 3
    • [Number of Catalog Items (i.e. Entities)] = 1
