Configuring the Microsoft Dynamics AX business database for better performance

Microsoft recommend the following settings for the Microsoft Dynamics AX business database. You can use SQL Server Management Studio or the appropriate ALTER DATABASE statement to configure these settings.

  • Set COMPATIBILITY_LEVEL to 110 for SQL Server 2012, or to 100 for SQL Server 2008 or SQL Server 2008 R2.

  • Set READ_COMMITTED_SNAPSHOT to on. Performance testing has shown that Microsoft Dynamics AX performs better when the READ_COMMITTED_SNAPSHOT isolation option is set to on. You must use an ALTER DATABASE statement to set this option. This option cannot be set by using SQL Server Management Studio.

    Run the following query, where <database name> is the name of the Microsoft Dynamics AX database. There can be no other active connections in the database when you run this query.

    ALTER DATABASE <database name>

    Query the sys.databases catalog view, and verify that the Microsoft Dynamics AX database contains a value of 1 in the is_read_committed_snapshot_on column. For more information, see the following Web pages:

  • Set AUTO_CREATE_STATISTICS and AUTO_UPDATE_STATISTICS to on. Set AUTO_UPDATE_STATISTICS_ASYNC to off. Performance testing has shown that Microsoft Dynamics AX performs better when the options have these settings.

  • Make sure that the AUTO_SHRINK option is set to off. When database files are automatically shrunk, performance of the database degrades. We recommend that the database administrator manually shrink the database files on a predefined schedule. For more information, see Turn AUTO_SHRINK OFF! on the SQL Server Storage Engine Team's blog.


All Microsoft Dynamics AX databases must use the same SQL collation. These databases include the business database, model store database, Microsoft SQL Server Reporting Services database, and Microsoft SQL Server Analysis Services database.

12 Ways to Improve Your Productivity at Work



Between constant meetings, phone calls and emails, staying productive at work can be a challenge. However, the odds of staying productive can be greatly improved by taking some simple steps in order to stay efficient.

Here are 12 tips from the team to help you to make the most of your time at work:

1. Don’t let emails take over your day

We are all so accustomed to email that as soon as we see a new email in our inbox we instinctively click it on, focus on the content of the email, and respond. These seemingly tiny activities during the day can quickly add up to large amounts of time that not only cause your day to slip away, but also distract you from completing your current task.

If replying to or disposing of an e-mail takes less than two minutes, do it right away. Send less to receive less: Keep your e-mails short, and write fewer of them. Here are some tips from the career experts at to help you control your work emails.

2. Eliminate unnecessary meetings

Face-to-face communication is essential (email is fraught with misinterpretation), but be ruthless about protecting your time. Avoid every meeting that isn’t truly necessary.

3. Learn how to say ‘no’

While everyone wants to be a good team player at work, saying ‘no’ is sometimes the right thing to do. If you are not the best person for a task, or if you have other pending deadlines, it is OK to turn down a work request.  read more

The administration of number sequences – AX 2012

The administration of number sequences is performed by using actions provided in the Administration group on the action pane on the Number sequences list page.

Organization Administration –> Common –> Number Sequences ---> Number Sequences


  • Status list

Provides a list of numbers that have been generated for continuous number sequences, but which have not been committed to the database. The numbers are either currently being used in a user session, are reserved for future use in a user session, or are free for use if a new client user session requests a new number for a particular number sequence in the list. If a new number does not exist for a specific continuous number sequence, it is generated by the sequence number framework from the next value for that number sequence in the Number sequence table (NumberSequenceTable).


  • Manual cleanup

Allows the administrator to manually clean up numbers in the status list. Use of this option is only recommended after an unexpected system failure; in such rare circumstances, numbers might not be automatically cleaned up.


  • History

Provides the history of changes to the number sequences themselves.



A number of administrator tasks can be performed from the Details page. An administrator can, for example, schedule an automated periodic cleanup for every number sequence by entering intervals on the Automatic cleanup FastTab as displayed in image below


An administrator can also assign number sequences by using a page in the parameters forms in individual application modules. For example, you can view or assign the number sequences to specific references in the General ledger module. You can navigate to the form by using the path General ledger > Setup > Parameters.


How to reset TTSBegin/TTSCommit in AX

We are using TTSBegin and TTSCommit when update and create a record in AX, but some times an error is occurred  and through an exception.

If we did not abort TTS by using TTSAbort  statement between try and catch keyword as below




// your update code







so we may facing this error below,

To fix this error please run the following job

static void ResetTTS(Args _args)
    while (appl.ttsLevel() > 0)
        info(strfmt("Level %1 aborted",appl.ttsLevel()));

Make sure that the X++ code has been compiled to Microsoft .NET Framework CIL - AX Batch Error

I developed custom class which extend RunBaseBatch system class to run in server, After created my class and run the class though batch job, there is an error is occurred and got the following error in log.

"Unable to construct an object from the class Sample Class in the batch framework. Make sure that the X++ code has been compiled to Microsoft .NET Framework CIL, and that the constructor does not require any parameters"

After search through internet I got solution by run “Generate incremental CIL” as  displayed below


Hint: May it takes time depend on server configuration.

Performance considerations for number sequences in Dynamics AX

Consider the following information about how the configuration of number sequences can affect system performance before you set up number sequences.

Continuous and non-continuous number sequences

Number sequences can be continuous or non-continuous. A continuous number sequence does not skip any numbers, but numbers may not be used sequentially. Numbers from a non-continuous number sequence are used sequentially, but the number sequence may skip numbers. For example, if a user cancels a transaction, a number is generated, but not used. In a continuous number sequence, that number is recycled later. In a non-continuous number sequence, the number is not used.

Continuous number sequences are typically required for external documents, such as purchase orders, sales orders, and invoices. However, continuous number sequences can adversely affect system response times because the system must request a number from the database every time that a new document or record is created.

If you use a non-continuous number sequence, you can enable Preallocation on the Performance FastTab of the Number sequences form. When you specify a quantity of numbers to preallocate, the system selects those numbers and stores them in memory. New numbers are requested from the database only after the preallocated quantity has been used.

Unless there is a regulatory requirement that you use continuous number sequences, we recommend that you use non-continuous number sequences for better performance.

Automatic cleanup of number sequences

In case of a power failure, an application error, or other unexpected failure, the system cannot recycle numbers automatically for continuous number sequences. You can run the cleanup process manually or automatically to recover the lost numbers.

Carefully consider server usage when you plan the cleanup process. We recommend that you perform the cleanup as a batch job during non-peak hours.

How to pass parameter to SSRS report from Dynamics AX

The below code for Passing parameters to SSRS using X++ code.


    MenuFunction SSRS_MyReport;

    Args Args;

    str parmId ="";


   // create reference to menu item “OverTime” which is in AOT
    SSRS_MyReport = new MenuFunction(menuItemOutputStr(OverTime),MenuItemType::Output);

    Args = new Args();

    // Set parameters and parameter value
    // I have 3 Parameters Nationality, EmplGroup, PeriodID

    parmId = "Nationality=KSA&EmplGroup=HERD&PeriodID=2014_05";

    // Assign parameters to report

    // Run the report;




1- Parameters name is case sensitive, so it should set name as predefined in report.

2- You can pass more than one parameters by add “&”   between each parameter.

3- Not add space between parameters, it cause an error
