Dynamics ax2012:How to export data using Runbasebatch

问题

I'm using Data Import Export Framework in Microsoft Dynamics AX 2012 in order to export custom data (TestTable) from ax to file. I successfully did that.

Now I want to create a Batch job manually and then assign Batch job tasks for Staging job and Export job to execute this export in background. I don't know how to implement it, now I'm trying to create my own batch by duplicating Tutorial_RunbaseForm class.

To learn how to set up execution jobs as batch jobs in AX I've started with Staging job:

Processing group > Get staging data > Create new job id > Select batch processing check box

and got the following infolog:

The Staging:ExportAXType-3 job is added to the batch queue.

In Processing group > Execution history my job has waiting status and when I click on the view staging data Staging data shows nothing at this point.

In System administration > Inquiries > Batch job I select my job and click on the View task button then Parameters button and an error is shown:

Cannot change a batch job that is not in the Withhold state

Update :

The export via batch don't work ,i found this error :

System.NullReferenceException: Object reference not set to an instance of an object.
