AX 2012 - SQL Server Collation


There is a difference in collation setting between SQL Server default collation setting used for system databases (Master, Model, Msdb, TempDB) and the Microsoft Dynamics AX database . Latin1_General_CI_AS_KS_WS  v.s. Latin1_General_CI_AS

 

Database Name
Collation name
AX2012PROD
Latin1_General_CI_AS
master
SQL_Latin1_General_CP1_CI_AS
model
SQL_Latin1_General_CP1_CI_AS
msdb
SQL_Latin1_General_CP1_CI_AS
tempdb
SQL_Latin1_General_CP1_CI_AS
 
 

It is recommended that the collations of user-defined databases match the collation of master or model. Otherwise, collation conflicts can occur that might prevent code from executing. For example, when a stored procedure joins one table to a temporary table, SQL Server might end the batch and return a collation conflict error if the collations of the user-defined database and the model database are different. This occurs because temporary tables are created in TempDB, which bases its collation on that of model.

 

If you experience collation conflict errors, consider one of the following solutions:

·        Export the data from the user database and import it into new tables that have the same collation as the master and model databases.

·        Rebuild the system databases to use a collation that matches the user database collation. For more information about how to rebuild the system databases, see Rebuilding System Databases (http://technet.microsoft.com/en-us/library/dd207003.aspx).

 

More information can be found here:

http://technet.microsoft.com/en-us/library/bb402915.aspx
Windows Collation Name (Transact-SQL)


Here you can find a good post that explain the difference between collation Latin1_General_CI_AS (United Kingdom) respect SQL_Latin1_General_CP1_CI_AS (United States).
It’s better to use Latin1_General_CI_AS collation because is a Windows collation and the rules around sorting unicode and non-unicode data are the same.

SSRS Report AX 2012 - The operation has timed out error message when you run a report in Microsoft Dynamics AX

Hi


About this problem, read below and test to find if this will have improved SSRS Report performance:

There is a process to change long running jobs so that they are run in a Pre-Processing way, so that all the data is prepared before the SSRS Report Window is started. This prevents the timeout problem, sometimes shown by the message ““A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond”

To change the report to run in these pre-processing way ( Similar Sales confirmation, Sales Invoice, etc. reports ), see this example below for the Dimension Statement report on how to change this:

 

1.    To find which object you need to modify, first look in the AOT > Menus, for the Menu where the report is
 
2.    View the properties on this to see the associated menu item. You can see below the menu item is “LedgerDimensionTransStatement”.

3.    Find this menu item in AOT > Menu Items > Output

…and look at the properties, make a note of the “LinkedPermissionObject”, in this case “LedgerTransStatement”

4.    Next in the AOT > SSRS Reports > Reports, locate LedgerTransStatement, then expand this out until you see the Server Methods. Make a note of the Server Method class, in this case “LedgerTransStatementDP”

5.    In the AOT > Classes, locate and open class LedgerTransStatementDP.

6.    In the LedgerTransStatementDP\classDeclaration, change line 9 to extend SrsReportDataProviderPreProcess instead of SrsReportDataProviderBase

7.    Make a note of the Temp table used in the report, as above this is LedgerTransStatementTmp.

8.    Next, change the method LedgerTransStatementDP\processReport to add the following line after the contract (line 27):

 

ledgerTransStatementTmp.setConnection(this.parmUserConnection());
 

9.    Next, in AOT > Data Dictionary > Tables, locate the table you made a note of in point 7, so in this case the LedgerTransStatementTmp. Change the table properties as follows:

 

·         TableType = Regular

·         CreatedBy = Yes

·         CreatedTransactionId = Yes

 

10. Opened LedgerTransStatement.Detail report in Visual Studio and refreshed the data source to include new field (CreatedTransactionId).

11. Deployed the new LedgerTransStatement.Detail report.

12. In AX, did a Generate Incremental CIL.

13. Restart SSRS

Office Add-in work also with a non Admin AX user

Hi all

If an AX user haven't Sys Admin Role and don't use an AIF service, can't read and publish data with Office Add-in

The workaround is :

1- Add privilege AIFGenericDocumentService to the Role Systemuser. This permit the access to the class AIFGenericDocumentService

2- Add the table AifGdsCache to the permission of the Role Systemuser. This table is necessary for the cache using by Add-in

3- Add to the user the role Systemuser and the roles related the specific area


With this workaround you can't add a table to Excel, but you can prepare a Excel file with an AX Admin user and share with other non Admin AX users.

Transactional Replication with AX

Below some link useful for activate transactional Replication in AX :

SQL Server topology


Here you can find a Class that goes through all the tables in the AOT. It checks to see if there is a primary key, then if there is not one, it will set the table to have a RecId Index (if not already set). The final step then makes the RecId index the primary key index.

AX 2012 - Upgrade Entire AOD

Hi

Today I was working on Upgrade from AX 2009 to AX 2012.

I moved the AXBUS.AOD with lots of Custom Objects into AX 2012.
After that, I have found a lot of standard tables and classes (on FPK Model Layer) with the method of the Custom BUS Objects!

The reason is related to the IDs. Practically the BUS Custom Objects of AX 2009 had the same IDs of the Standard Objects (On FPK Model Layer) in AX 2012

AX 2012 - Identifying a user session in SQL Server

HI

In previous versions of Microsoft Dynamics AX, the Online users form contained a column that provided a session process ID (SPID) for each client session. This column was useful for debugging blocked sessions. Specifically, the SPID column was used to find a user session that corresponded to a specific SPID. In Microsoft Dynamics AX 2012, the SPID column is no longer available in the Online users form.
  
In Microsoft Dynamics AX 2012, information about the user session can be included in the connection context for Microsoft SQL Server. because the inclusion of this information has a small effect on performance, the functionality is not turned on by default.
 
So, if you want to add again SPID column in the Online users form, you have to :
 
  1. Click Start, click Run, type regedit in the Open box, and then click OK.
  2. Locate the following registry key:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Dynamics Server\6.0\01\Original (installed configuration)
    The Original (installed configuration) key is the key name for the current server configuration, if the configuration has not been changed from the default. If your system uses a configuration other than the configuration that was originally installed, locate the configuration that is currently active.
  3. Right-click the key, point to New, and then point to String value. Name the new value connectioncontext, and set the value to 1.
  4. Close the registry editor.
  5. Start the Services snap-in, and then restart the Application Object Server (AOS) service.

Find session information

  1. Open Microsoft SQL Server Management Studio.
  2. Run the following query to view all sessions that are related to Microsoft Dynamics AX:
    select cast(context_info as varchar(128)) as ci,* from sys.dm_exec_sessions where program_name like '%Dynamics%'
    The first two items in the ci (connection information) column are the Microsoft Dynamics AX user ID and the session ID.
  3. In the Online users form, you can now identify each session.

Object Server xx: Internal Error occurred executing stored procedure when creating session for the AOS

Hi Guys

If during the AOS Service starter have the error "Object Server xx:  Internal Error occurred executing stored procedure when creating session for the AOS" means that the Store Procedure CREATESERVERSESSIONS and CREATEUSERSESSIONS are missing in the Database.

At this point you have two solutions :

1- Create the Store manually
2- Install again the AOS service

I prefer the second solution !

Synchronize Database Problem - Missing Field in SQL Table

Hi

During Syncronize process could happen that for certain Tables the System table SqlDictionary present all columns, but the relative SQL Table have some fields missing.

The problem occur with the Check\Synchronize Action. Seems that AX update correctly the system table SQLDictionary, but don't create the new fields in the SQL Tables.

Due to solve the problem, run the Synchronize Database Action from the SQL Administration form. This action first update the system table SQLDictionary and finally create the fields in SQL Table if missing.
Seems that the Check\Synchronize Action, if a field is present in the system table SQLDictionary don't check if the same is present in the SQL Table !

AX 2012 - The DefaultValue expression for the report parameter ‘AX_CompanyName’ contains an error

We run into issue that whenever we used a Microsoft Dynamics AX configuration file with a Reporting Services instance (as mentioned in here: http://technet.microsoft.com/en-us/library/hh389774.aspx) the following error was reported the first time a report was run after the restart of the SQL Reporting Services instance:
"The DefaultValue expression for the report parameter ‘AX_CompanyName’ contains an error: Request for the permission of type 'System.Security.Permissions.EnvironmentPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed. (rsRuntimeErrorInExpression)"
Running the report for the second time, it renders without any error. The error is mostly seen with subsequent instances of Reporting Services because only then an Microsoft Dynamics AX configuration file (Microsoft.Dynamics.AX.ReportConfiguration.axc) is used but any Reporting Services instance that is set up to use an AX configuration file will throw this error.

The resolution we found was to use "FullTrust" permission set in place of "Execute" for the "Report_Expressions_Default_Permissions" in the rssrvpolicy.config but maybe there is some other solution that I was not aware of.
