SSRS Reports - Showing the first record's data of your group

 If you need to display the first record's data of your group, you can use the following expression:

=First(Fields!FieldName.Value, "GroupName")

AX SSRS Report - How to modify parameter properties based on usage data values

I have a report type parameter that determines which parameters the report needs to run.
I created a new enum for the Report type, available options are Job Number or Invoice Number.

If the job number is selected there will be a start job number and end job number with labels "Starting number" and "Ending number." If Invoice Number is selected there will be a start invoice number and an end invoice number with the exact same labels.

Since the job number is the first enum, I decided to build the parameters as if Job number were selected. However, if the user selects invoice number and that is stored in usage data, the parameter screen would need to accommodate that and show the correct parameters based on the invoice number report type selection.

I created a UI Builder class to accomplish this. My report is already using a contract class to define the 5 parameters I need for the report, a controller class, and a DP class to process the report. In the build() method of the UIBuilder class, I add all the dialog fields I will need and then I set visible = false for the invoice start and end fields.

In the postRun() method (before the super()), I check the value of the reportType enum. PostRun() gets called after the usage data is stored in the field(s). If the reportType is InvoiceNumber, I set the jobstart/end fields to visible = false and the invoicestart/end fields to visible = true.

This works nicely. 

I also had to override the modified method of the reportType parameter in order to change the parameters shown when the user modifies the report type. For this, I used the postBuild() method tell the system to override the modified() method and where to go to find the new logic for this method.

Ensure that you use the right form control for your field type. For example, my enum reportType is a comboboxcontrol. If your field is a string, you would need a FormStringControl. If your field is an Int you would need a FormIntControl, etc. Your modified() method will need to pass that same type of control as well.

Good luck!

Dynamics AX 2009 - removing new line character from string (note/memo/text) fields

So this is my first post on this dynamics AX blog of mine. I'm going to use this to keep track of the little programming solutions I develop. Maybe it will help someone else too. Who knows?

My customer was having problems with a report showing the delivery address in excel. When a new line character is reached, it moves to another line. This made the excel format untenable for our 3rd party vendor that needed the data. So I wrote this code on the report to strip the new line character out and replace it with a space.

display str DeliveryStreet()
{
TextBuffer txt = new TextBuffer();
;

txt.setText(dataSource.DeliveryStreet);
txt.replace('\n',' ');
dataSource.DeliveryStreet = txt.getText();

return(dataSource.DeliveryStreet);
}

The DeliveryStreet field on the report calls this method instead of calling the field on the datasource.
