Errors when using <Current BPS Connection>

0

Hi Jacek,

there was a time before the connection existed. It was introduced at some point and than the bps_user was introduced.
It's more secure but adds a little problem like the one you found.
I encountered the same message when trying to read data from a separate attachment database. Since it's a local user, it doesn't have access to the other database.

Options I found so far:
- Creating a view in the current database and grant permissions to it.
This is not really an option, I don't want to change the queries.

- Add Module signing
I have not really understood it. Maybe it creates a new object in the current database which is allowed to access data in another database. Regardless if this correct or not, the sql statement would need to be modified.
https://dba.stackexchange.com/questions/193259/access-view-based-on-table-in-another-database-without-account-in-that-other-dat

So I switch to an own database connection with a readonly sql user to the necessary databases. It's easier to switch the connection than to modify the query.
It may even be possible to change this with an update statement. But I haven't tested it.

Best regards,
Daniel

Thanks for your answer and hints. I haven't found better solution than change to dedicated connection and alternatively change querry a bit.
It doesn't resolve problems with data source filters or report counted columns, but it works in most cases.
