Multivalue report parameter default value from second datasource

[Jiri]

Hi

my report has two sqlDataSources: first is bound to report as report data, the second is bound to multivalue parameter as data source (and selected value from this parameter is used as a filter). Now I need to set default value for that parameter using expression, but fields are available only from first (report bound) data source. Is it possible to address field from second data source in expression? If not, how to select default value from second expression programmatically?

Thank you in advance,

Jiri

Hi Jiri,

You can specify the default value for Multivalue Report Parameters using Aggregate Functions. You can also create a Custom Aggregate that will select the default values, according to your needs. There is a guide on how to implement this approach in the following article: Using Multivalue Parameters.

All the best,
