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.

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”)

Dev Tip: Activating document handling for inquiry(read only) forms – Dynamics Ax 2012

September 20, 2013 Leave a comment

This post will explain how document handling can be activated only for specific tables or for all tables.

Activate document handling for selective tables.

To activate document handling for selective tables.

Go to Organization administration -> Setup -> Document management -> Document management parameters

Check the flag “Use active document tables

selective_active_document

Once specified here then document handling is active only for selective list of tables. To specify the active list of tables  go to Organization administration -> Setup -> Document management -> Active document tables. Document handling is now only enabled for the selected tables in a controlled mode.

active_doc_table

Activate document handling for all tables.

Simply unchecking the  “Use active document tables” in Document management parameters makes it activate for all tables. There is a limitation here, in the case where document handling is enabled for all tables the system verifies if the table has edit/delete permission. Only if it is the case document handling is activated otherwise it is disabled. E.g This means tables like Salestable/Salesline will have permission to add/edit documents while forms that uses tables like custInvoiceJour, vendinvoice jour will have document handling disabled.

User’s may ask for document handling to be activated on these read only  forms. In these case there is a way out.

Go to Organization administration -> Setup -> Document management -> Active document tables and enter the table name, say “VendInvoiceJour” also make sure to check the “Always enabled” flag. This is very important since this means the document handling is enabled irrespective of the table permission. So this way you can activate document handling for read only tables

alwayenabled

\Forms\DocuView\Methods\doReSearch – Go to this method

on line Number: 130 – add the following line,

allowEditBasedOnActualForm = true

codeimage

Setting this will enable you to use the full document handling feature even for read only forms.

SSRS tip: No row message in Dynamics Ax SSRS 2012

September 9, 2013 13 comments

Some sections in your report may not have data but the header sections  might print. In these cases to make it informative for the user a “No data available” message might be helpful since the user is then assured that there is no data for that particular data section. This tip will guide you on how to setup “No data available”.

Select the Tablix/List/Matrix control where you want the message to be available and open the properties window, Find the property “NoRowsMessage”. This property can be filled in with text or for dynamic text using expressions. Type in something like “No data available”

2013-08-30_1553

When there is no data for that particular section SSRS automatically prints the text under “NoRowsMessage”

SSRS tip: Take care that VS and AX client are in the same layer for SSRS – Dynamics AX 2012

September 5, 2013 14 comments

Some times when you use configuration files to start your AX client like this in the image and also work on visual studio, make sure your default client configuration is pointing to the same layer as in the configuration file.

2013-08-30_1528

This is because the Visual studio opens in the layer that is specified in the default settings in AX Client Configuration window. Though your AX client is on VAR layer if your default client configuration setting is pointing to the USR layer then the visual studio reporting project gets saved to the USR layer. You end up in deleting and reimporting the entire project. So make sure to verify the layer setup before you start working on reporting projects.

To setup the default layer configuration, 

Open the run window and type axclicfg

In the window that opens create a new configuration or on the existing configuration go to the Developer tab and verify the layer information including the license

Dynamics Ax 2012 Security How To – Book Review

December 21, 2012 2 comments

Packt has recently come up with a Security How-To book to followup it’s Ax2012 releases.

 

7508ENcov.jpg

Thanks to Packt for asking me to review their book and I appreciate the author Ahmed Mohamed Rafik Moustafa for his work.

First of all, this is not the regular books that keeps you stay away from reading by the sheer numbers of page. I like the fact that Packt is trying to come up with more shorter series that are interesting and easier to read. The security How To is a Hand book with less pages and more content. It is something that you can tap on to your smart devices, start reading on your way to meet your client and be fully prepared.

The book inclines more towards administrators and consultants but it still dedicates few of the topics to the hard core developers who double as consultants. Segregation of duties to meet Sox Compliance or similar standards was not at least a cake walk with the previous versions of Dynamics Ax. Ax 2012 has made it much easier for functional users/administrators to carry out this operation, but that also means that you need to understand this new framework.  For that matter this book can come handy to get you prepared to face this new framework.

Right now Packt is running a offer and you will be able to buy this book for a little more than a dollar and i definitely recommend that you do it, since the take away from it is worth it. Click here to buy it
