Error: SSRS/EP error when the return type in display method is incorrect – Dynamics AX 2012

October 11, 2013 1 comment

When you work with data sources through a query in EP/SSRS you might land up in this error “Data or calculated fields with type “Record” are not supported”.

Record_type_error (2)

How do i resolve ?

One of the tables that is being used in the data source has a display method with a return type as “record”.  Scan through all the display methods and find the one that has the display keyword but still returns a type record in the signature. In our case we had a method similar to this

    Public display inventTable getInventTable()
    {
         return InventTable::find(this.itemid);
    }

Why does this happen ?

It is illegal to use a display keyword for a method that returns any complex object like “Container”, “Record”, “Class”. The reason we don’t find it inside AX is because compiler doesn’t validate it and it can be deducted only at run time. So say you have you a display method as in the example above but you never use it then AX never complains about it.

When these tables are accessed through Query in SSRS, SSRS tries to run through the list of display methods to show up in the field selection. Since SSRS cannot comprehend the return type it throws this error.

Issue: Dimension lookup “selected record invisible” – Dynamics AX 2012

October 7, 2013 Leave a comment

On a server machine which was used for UAT testing the users were complaining about the selected record not visible in the lookup as seen here,

As we all know the financial dimension lookup uses the segmented entry control which is a managed control. Segmented entry control being a managed control we have limited handle to the behaviour and appearance. So after some search around we ended up that it was a windows theme related issue. If you happen to use AX2012 on a server machine (Windows Server 2012) or using the VPC you may notice this issue.

The solution is to change for a better theme, but hold there is a point there. By default windows server 2012 doesn’t allow you to change the theme. This feature is called a “Desktop experience”, this must be enabled to activate the the personalize option through which you can change the theme. See here on how to enable desktop experience for Window server 2012  http://www.win2012workstation.com/desktop-experience/ . If you are on a standard Microsoft Dynamics AX VPC machine then desktop experience is already enabled. You just need to make the choice of a better theme. Once we had changed our theme the lookup looked much better.

Productivity tip: Do you need the under score when naming – Dynamics Ax

October 4, 2013 Leave a comment

Well When we sat through the product review there was one simple point that caught our attention, surprisingly it helped us improve our productivity. This post is to share on what we learnt.

Typically i have seen several implementation and product development teams adopting the ‘_'(underscore) naming convention. In fact we followed it through out Dynamics AX 2009. Though at the very first look it appears helpful in hindsight it deters productivity.

How ?

1. While you type holding a shift key is not making typing faster.

2. Every time you declare a variable you are again held up with underscores

3. On the AOT node navigating is definitely not easier.

If you look all these points at a component level it can be ignored but when you do it over and over it adds up to a significant time.

Next time you start a new project or product consider if you need to use the underscore ‘_’ again.

Producvity tip: Don’t scroll use Ctrl + G in your Editor – Dynamics Ax

September 27, 2013 Leave a comment

The other day as i was reviewing a code modification to a long method from my team mate he had to walk me up and down through the code scrolling.

Just then the Ctrl + G flashed in me. Yes It takes a lot less effort to type in the line number then scrolling up and down. Even if you are not sure of the line number make it a guess then it is always a few lines up or down.

Go_to_line

If you are newbie here is how you can find the line number

On AX 2009 

You can identify the line number in the status bar.

2009_LineNum

On AX 2012

Activate the toggle line number in the tool bar or identify the line number from the status bar

Ax2012_LineNum_001

Best practice

Ideally keeping best practices in mind you must right methods that have limited number of lines and break them and keep it modular.

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 1 comment

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”)
