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.

  1. Understand the inners of reporting Framework: This book helps you understand the framework portions like the controller, preprocessing, temptable marshaller to the depth with the help of flowcharts and diagrams. Just because you do it better when you know it better.
  2. Better choice of controllers and data source: The book has one or more examples for all the possible controls including the ones that are not found in the out of the box reports and discusses every possible data source available for the reports with examples. Just because you make a better choice when you know the options better.
  3. Speed up development and testing: Inside the book there are unique techniques that can help you speed up development as well gain time by quick tricks to fasten testing. Just because you get time to be creative when you make your routines easier.
  4. Implementation pattern reference: There are recipes in this book for typical development patterns like validations, defaulting values, building lookups, multi value lookups, inventory & financial dimensions and much more. Just because Google is not your only friend we are here too 🙂
  5. Analyze and Handle issues faster: The book has step by step in detail guidance to approach development issues, upgrades and design. It speaks about additional tools that can help you understand report performance and usage. Just because your mysterious must not remain unresolved.

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”)

SSRS Tip: Using invisible parameters in contracts – Dynamics AX 2012

September 18, 2013 3 comments

There can be cases where you wanted a contract in the attribute but do not want the UI builder to expose it to the user. The reporting framework in AX provides a very easy way to incorporate this.

Open the parm method in the contract that you don’t want to expose. Add the attribute shown here along with other attributes. This attribute when found in the parm method will automatically prevent the UI builder from adding this to the dialog.

[DataMemberAttribute, SysOperationControlVisibilityAttribute(false)]
public LogisticsAddressing parmAddress(LogisticsAddressing _address = companyAddress)
{
companyAddress = _address;
return companyAddress;
}

This feature comes as a part of the BOF, see here http://j.mp/185ufd2

Update: Apologize for the wrong statement here. The only way to make a parameter visible when using the contract with reporting framework is to specify it in the design. This is because the contract class \Classes\SrsReportRdpDataContractInfo\buildMemberAndNestedObjectMap – 29 ignores this attribute and reads the design RDL (created using your VS) to decide if a parameter must be visible in the contract. So to hide your parameter open the parameters node in Visual studio and then set the visibility property to hidden.Also a point to understand is that the VS design overrides any specifications at the contract level for properties like  LableHelp, Visibility, grouping, HelpText, value type (multivalue) etc. (Ref: \Classes\SrsReportRdpDataContractInfo\fillReportDesignProperties). Thanks to a AXForum member who pointed this out.

SSRS Tip: Using labels for dynamic texts in SSRS reports – Dynamics Ax 2012

September 16, 2013 9 comments

Dynamic text in the reports makes them more readable and meaningful. In this article we will see how we can use labels from  AX to construct your dynamic text. The string format option comes handy to help us do this.

Here is how you must specify a string text with labels in it.

Open the report control properties and on the property “Value”, select the expression option and place your text in the format seen here.

=System.String.Format(“This is a label id converted at run time {0}”, Lables!@SYS1560);

You can also use report or data base fields like Fields!CustTable.Value to construct your Dynamic text.

SSRS Tip: Speed up RDP based SSRS reports testing in Dynamics Ax 2012

September 11, 2013 15 comments

When working on precision designs a lot of time is spent on waiting for the preview to run. If your precision design uses an RDP dataset here is a simple and fantastic tip to speed up.

1. Convert your temporary table to persistent by modifying the TableType property to Regular

2. Now run the report once. Either from Visual studio or inside Ax. This fills the data in the temporary table.

3. Comment the code inside processreport method or simply write a “return” statement on the first line of the method.

That’s it. you are now geared for a faster execution of the reports. Remember to revert back once you are done or wait for the testers to find it 🙂 but don’t let it go to the production.
