Can you try creating both datasets and then drag the first one
(userclient one) onto the canvas, then nest the second dataset/table
into the first one. This should cause your first dataset to be called
and then your second one.

this is an older video and uses normal datasets, but it should give you
the idea.

I think for the table to show up when dragging, the sp must return a row
set. Another option may be to use the data engine api in script to call
the stored proc. Take a look at the attached example. You will not be
able to run it but you can look at the script in the beforeFactory.

Thanks Jason,
I had a go at incorporating the scripted SP in the beforeFactory, but its still not returning the executed SP before the dynamic list parameter. It seems strange that BIRT does not support this type of parameter functionality, unless i'm missing something (which is most probably the case). It's basically a case of prioritising the SP before the parameter execution since the SP works perfectly without the parameter...
Would you be able to tell me if this is on the right track?
I altered the script as such:
importPackage( Packages.org.eclipse.birt.report.model.api );
importPackage(Packages.java.lang);
importPackage(Packages.java.util);
importPackage(Packages.org.eclipse.birt.data.engine.api);
importPackage(Packages.org.eclipse.birt.report.model.api);
importPackage(Packages.org.eclipse.birt.data.engine.api.querydefn);
importPackage(Packages.org.eclipse.birt.data.engine.core);
importPackage(Packages.org.eclipse.birt.core.data);
rowcount=0;
var myconfig = reportContext.getReportRunnable().getReportEngine().getConfig();
var de = DataEngine.newDataEngine( myconfig, null );
var dsrc = reportContext.getDesignHandle().findDataSource("HRPO_STANDARD");
var odaDataSource = new OdaDataSourceDesign( "Test Data Source" );
odaDataSource.setExtensionID( "org.eclipse.birt.report.data.oda.jdbc" );
odaDataSource.addPublicProperty( "odaURL", dsrc.getProperty("odaURL").toString() );
odaDataSource.addPublicProperty( "odaDriverClass", dsrc.getProperty("odaDriverClass").toString());
odaDataSource.addPublicProperty( "odaUser", dsrc.getProperty("odaUser").toString() );
odaDataSource.addPublicProperty( "odaPassword", "/*db password*/" );
queryText = "{call SI0WPR_SET_IDENTIFIER (?,?,?)}";
var dset = new OdaDataSetDesign( "authenticateSP" );
dset.setDataSource( odaDataSource.getName( ));
dset.setQueryText( queryText );
dset.setExtensionID( "org.eclipse.birt.report.data.oda.jdbc.SPSelectDataSet" );
inputParamDefn = new ParameterDefinition( "user1",DataType.STRING_TYPE );
inputParamDefn.setInputMode( true );
inputParamDefn.setPosition( 1 );
inputParamDefn.setDefaultInputValue( "ADMIN" );
dset.addParameter( inputParamDefn );
inputParamDefn2 = new ParameterDefinition( "client1",DataType.STRING_TYPE );
inputParamDefn.setInputMode( true );
inputParamDefn.setPosition( 2 );
inputParamDefn.setDefaultInputValue( "DEMO" );
dset.addParameter( inputParamDefn2 );
outputParm = new ParameterDefinition( "desc_cliente",DataType.STRING_TYPE,false,true );
outputParm.setPosition( 3 );
dset.addParameter( outputParm );
paramBinding = new InputParameterBinding( "user1",new ScriptExpression( params["__userAppl"]) );
paramBinding2 = new InputParameterBinding( "client1",new ScriptExpression(params["__clienteAppl"]) );
de.defineDataSource( odaDataSource );
de.defineDataSet( dset );
queryDefinition = new QueryDefinition( );
queryDefinition.setDataSetName( dset.getName() );
queryDefinition.addInputParamBinding( paramBinding );
queryDefinition.addInputParamBinding( paramBinding2 );
queryDefinition.setAutoBinding(true);
colBinding = new Binding( "myoutputparm" );
colBinding.setExpression( new ScriptExpression( "outputParams[\"desc_cliente\"]" ) );
queryDefinition.addBinding( colBinding );
var pq = de.prepare( queryDefinition );
var qr = pq.execute( null );
var ri = qr.getResultIterator( );
while ( ri.next( ) )
{
rowcount++
ob = ri.getValue( "myoutputparm" );
}
ri.close( );
qr.close( );
de.shutdown( );

Daniel,
Maybe I am missing something. Is the data set you want to run after the
SP tied to a report parameter dynamic list?
