Data Reduction Using Section Access

wgonzalez — Mon, 26 Jan 2026 18:19:17 GMT

Hi,

I'm having issues with my implementation of Section Access. It is performing an unwanted data reduction. In the Presentation qvw, it is reducing by Function field which is not intended. It it doing this even though I'm in the SA table with ADMIN access. The reduction field is SUPVID. Please see table and attached image.

ACCESS	USERID	PASSWORD	NTADMINACCOUNT	SUPVID
ADMIN	*	*	AM\ADMIN1	*
ADMIN	*	*	AM\ADMIN2	*
ADMIN	*	*	AM\ADMIN3	*

ACCESS	USERID	PASSWORD	NTACCOUNT	SUPVID
USER	*	*	AM\USER1	12345
USER	*	*	AM\USER2	67890
USER	*	*	AM\USER3	24681
USER	*	*	AM\USER4	*

See attached image of data model.

There are only 3 SUPVID values listed in the SA table. The * value will only match those 3 SUPVID values. Are there more values?

Hi Craig,

The values in the table above are examples only. There are several ADMIN users and ~ 50 SUPVID values in the real data model.

I would recommend reviewing the following Design Blog post, and there are some additional links toward the bottom of the post, one is a You Tube video on how to make the Section Access table visible in the data model to do some further testing on the reduction fields.

Here is Help link too:

The key thing you must understand is * means according to data you are loading, those users will only see SUPVID 12345, 67890 and 24681, that is it, * only includes the other loaded values, any other values will not be included. If you leave the SUPVID blank, that should work in Desktop Client, but if you try to use that user to open via Server, the app will not open if Strict Exclusion is set in the document properties, just FYI. You would need to create a reduction value for all values or something along those lines in that case. Hopefully this gets you on the right track.

Brett

Hi.

In this case the intended final result is to provide access to all data for users with asterisk in column SUPVID, those with specific ID in that column should only have access to data records having a matching ID number. I’m wondering why it’s not working. Everyone is viewing everyone’s records.

Could anyone advise? Thanks.

This a sample data model for my question.
