SSRS Tip: Prevent report execution through controller – Dynamics Ax 2012

September 25, 2013 Leave a comment

What a user might hate to see is a blank report. No matter where the mistake lies the earlier we react the happier the user is. Here today i’m sharing a tip on how you could stop/warn/show a info after the report execution is initiated  after the user clicks the “Ok” button in the dialog.

In the example discussed here, the idea is to check preemptively if a query will return a record or not. If no then the report aborts execution.

To implement this, open the controller of your report or create one.

On the controller class, override the method “preRunValidate”

Place the code as shown here. This method is invoked after the user clicks the “Ok” button and before the report is executed. Do not block the super call in this method as it does few other important validations. This method can return an error/warning/info. If it is a warning or error the report aborts further execution.

protected container preRunValidate()
{
    container   validateResult = super();
    Query       firstQuery;
    int         recordcount;

    firstQuery          = this.getFirstQuery();
    custStatementCount  = QueryRun::getQueryRowCount(firstQuery, 6);
    if (custStatementCount > 5)
    {
        validateResult = [SrsReportPreRunState::Error, "No valid records found for the specified range"];
    }

    return validateResult;
}

Standard recommends the method to be used for validating if the report returns a large amount of data.For reference see \Classes\CustAgingReportController\preRunValidate\

SSRS Tip: Printing Row headers in every page – Dynamics Ax 2012

September 23, 2013 2 comments

This post today will discuss how to print row headers in every page for tablix.

When your table has a header

When using table type tablix with headers as seen in the below image, right click on the Tablix properties and select “Repeat header rows on each page” (If you use a matrix control please check the same for “Repeat header columns on each page”)

RepeatHeader

When you use a static tablix member in Row or Column.

If you don’t realize what a static tablix member, select a table and insert a row using the option “Outside Group – Above” or simply Insert Row -> Above if you don’t have any groupings. Now open the Group mode window (if not open, click the grouping icon from your report tool bar grouping_windo) and then click Advanced mode. The system will show up static members in a table. These are members that are calculated once and are rendered in one or multiple pages. These controls can also be used like headers.

Coming back, Once you have identified the static tablix member you want to repeat, On the property of the tablix member set “RepeatOnNewPage” to True. (If this doesn’t work outright, try setting the property “KeepWithGroup”  to “After”)
