AX 2012 R2 AIF Inbound Port - Exception

(0) ShareShare
ReportReport
Posted on by Community Member

Hi,

based on a query for two tables I have created the AIF documents and classes with the „AIF Document Service Wizard“.

I have only implemented the create-operation.

I also created an Inbound port based on a file-adapter for this service.

When I try to import a valid xml file, I get the following AIF-exception:

„The request failed with the following error:  

Unable to cast object of type 'Dynamics.Ax.Application.AxCommon' to type 'Dynamics.Ax.Application.AxMyTableName.“

Subsystem: AifInboundProcessingService-processRequest

Does anyone have an idea on what to do?

    Try to debug the code to see where the wrong type is coming from. See Walkthrough: Debugging AIF Service Operation Calls When Using File System Adapter, if needed.

    Hi,

    it's a long time you posted this question. I have been dealing with the same issue so I will post my solution, so that it may help anybody in the future.

    The cause of the error in my case was, that a <MyTableName> was too long and when AX generated an AX<MyTableName> class, it cut the class name to something like "AXMyTableNam". This must have been the problem because when I shortened the table name and regenerated the AX<MyTableName> class (using Ax menu > Tools > "AIF" > Update document service), it solved the issue.

    MSDN most probably specifies that by saying: "Each Ax <Table> class has a one-to-one relationship with a database table. This relationship is reflected in the naming convention for Ax <Table> classes. Names are constructed by prefixing the table name with Ax. For example, the Ax <Table> class for the SalesTable table is AxSalesTable." (https://technet.microsoft.com/cs-cz/library/aa873749.aspx).

    I had to change the new class name in all occurences in the code as well and had to re-register the my document service.

    I hope this may help somebody if needed.
