How to implement analysis authorization in BW to function with BO reporting through relational connection?

Hi experts!

I'm looking for example or workaround how to force a BW analysis authorizations to work in BO reporting tools through relational connection (UNX universes).

It functions perfectly through OLAP (BICS) connection in conjunction with the BEx authorization variable + SSO + SAP authorization.

When I launch a WEBI report based on relational connection certainly without a BEx authorization variable I get an error

The same report run fine under the user who have 0BI_ALL authorization object.

And the following is the analysis authorization trace in RSECADMIN.

Thanks in advance!
