Try Catch example code

Klaas Deforche — Tue, 09 Aug 2011 18:04:50 +0000

Hi all!

The code below contains a try/catch that I use a lot when developing batch jobs, especially multithreaded ones.
It deals with frequently occurring exceptions that, in some cases, can be easily solved by retrying:

Deadlocks
Update conflicts
Duplicate key conflicts

Duplicate key conflicts are more rare than update conflicts, but I’ve seen them pop up under heavy load on InventDim records.

try
{
ttsbegin;

// do stuff here

ttsCommit;
}
catch (Exception::Deadlock)
{
// retry on deadlock
retry;
}
catch (Exception::UpdateConflict)
{
// try to resolve update conflict
if (appl.ttsLevel() == 0)
{
if (xSession::currentRetryCount() >= #RetryNum)
{
throw Exception::UpdateConflictNotRecovered;
}
else
{
retry;
}
}
else
{
throw Exception::UpdateConflict;
}
}
catch(Exception::DuplicateKeyException)
{
// retry in case of an duplicate key conflict
if (appl.ttsLevel() == 0)
{
if (xSession::currentRetryCount() >= #RetryNum)
{
throw Exception::DuplicateKeyExceptionNotRecovered;
}
else
{
retry;
}
}
else
{
throw Exception::DuplicateKeyException;
}
}

AIF: There is no service with namespace = ‘http://yournamespace’ and external name = ‘aService’.

Hi all :-)

Today, when testing newly deployed AIF web services, this error was thrown:

There is no service with namespace = ‘http://yournamespace’ and external name = ‘aService’.

Where ‘http://yournamespace’ is the namespace you specified on the service node in the AOT, and ‘aService’ is the external name of your service.

The problem is that on the service node of this service in the AOT, there was a ‘/’ (slash) at the end, like this:

Removing the slash at the end fixes the problem:

I did a refresh in the Service form and redeployed my services on the IIS, so you might have to do that too.

Cannot edit a record in Translation table (DEL_PBATranslateConsistOf). Access Denied

Klaas Deforche — Sun, 29 Aug 2010 11:54:23 +0000

When deleting a company account in Dynamics AX 2009, you can get the following errors:

User ‘Admin’ is not authorized to delete a record in table ‘DEL_PBATRANSLATECONSISTOF). Request den[ied].
Cannot edit a record in Translation table (DEL_PBATranslateConsistOf). Access Denied: You do not have sufficient authorization to modify data in database.

This week was the n-th time someone has come to me with this problem, so it’s time to blog about it :-).

The error you receive is odd, because user in question has enough rights to edit any table (administrator).
This error occurs when you don’t have the Product Builder (PBA) license key enabled.

There are two possible solutions to this problem:

Either activate the license key for Product Builder under Administration – Setup – System – License information (if you have the PBA license key), and after synchronizing the Data Dictionary, you should be able to delete the company account
Or if you don’t have the PBA license key, go to the AOT – Data Dictionary – Tables – DEL_PBATranslateConsistOf, and clear the security key property.

AllowDuplicates Yes: Illegal property value

Klaas Deforche — Mon, 17 May 2010 16:06:22 +0000

When changing the property AllowDuplicates on a table index from No to Yes, the following error can be thrown at you:

Illegal property Value

This is because on your table, the property PrimaryIndex is set to the index you are trying to change.

AIF: ‘EndElement’ is an invalid XmlNodeType

Klaas Deforche — Tue, 20 Apr 2010 09:31:08 +0000

Hi all.

I got this error when developing a C# .NET application that consumed a AIF web service, and couldn’t find a solution online so let me share mine :-).

The problem was that I initialised my queryCriteria wrong:

CriteriaElement ace = new CriteriaElement();
ace.FieldName = "AccountNum";
ace.Value1 = "000001";

I forgot the specify the datasourcename and operation:

CriteriaElement ace = new CriteriaElement();
ace.FieldName = "AccountNum";
ace.Value1 = "000001";
ace.DataSourceName = "VendTable";
ace.Operator = Operator.Equal;

AIF: HTTP Error 404.3 – Not Found

Klaas Deforche — Mon, 19 Apr 2010 14:34:24 +0000

After installing an AIF web server and deploying services on it, I got an error when I tried to browse my web service http://myhost:82/MicrosoftDynamicsAXAif50/itemservice.svc.
The error was:

HTTP Error 404.3 – Not Found

When I tried to add a web reference the svc in visual studio .NET, I got a similar error:

HTTP Error 404 – Not Found

I solved it by using the method described on the AIF blog:
http://blogs.msdn.com/aif/archive/2008/12/12/http-error-404-3-is-received-when-calling-a-web-service.aspx

Basically, execute the following command on your web server:

ServiceModelReg.exe -i -x

After that, everything worked fine.

AIF: The path %1 does not exist or is not accessible from an AOS server. Always use a UNC path.

Klaas Deforche — Tue, 08 Dec 2009 17:03:27 +0000

Hi guys,

It seems like I’m going to be doing a lot of AIF in the future, so I’d like to share the first AIF error I came across:

The path C:\AIF does not exist or is not accessible from an AOS server. Always use a UNC path.

You can get this error when setting up channels.
While I immediately know what the problem was (you have to use shares), my less technical-minded colleague didn’t know what to do.

This is what Wikipedia has to say about ‘UNC path’:

The Microsoft Windows UNC, short for Universal Naming Convention or Uniform Naming Convention, specifies a common syntax to describe the location of a network resource, such as a shared file, directory, or printer. The UNC syntax for Windows systems has the generic form:

\\ComputerName\SharedFolder\Resource

So there you have it, you have to use a shared folder in stead of a local folder.
This is logical, as AIF runs on server, and the AOS can not access your local folders.

Error code 122 while exporting xpo

Klaas Deforche — Fri, 05 Jun 2009 13:12:45 +0000

While exporting code from Dynamics Ax to an xpo file, I received the following error:

Error in file: C\DOCUME~1\SRV_TR~1\LOCALS~1\Temp\$tmp00040005$ while writing in record = D8AA0
Windows error: =
Error code: 112 = Unknown Error

Error code 122 means (msdn):

ERROR_DISK_FULL: There is not enough space on the disk.

The problem here is that the AOS is trying to create a file, but there is not enough space on the hard disk to do that.
You can solve this problem by freeing up disk space on the AOS. After you did that, exporting will work again.
