{
}

[DataContractAttribute]
public void xmlGeneration(Args _args)
{
XmlDocument doc;
XmlElement nodeXml;
XmlElement nodeTable;
XmlElement nodeAccount;
XmlElement nodeName;
CustTable custTable;
#define.filename(@'C:\\Users\user\Desktop\productsXML.xml')
;
doc = XmlDocument::newBlank();
nodeXml = doc.createElement('xml');

doc.appendChild(nodeXml);
//Determines the runtime
if (xSession::isCLRSession())
{
info('Running in a CLR session.');
}
else
{
info('Running in an interpreter session.');

//Determines the tier
if (isRunningOnServer())

}

}
}

while select custTable
{
nodeTable = doc.createElement(tablestr(CustTable));
nodeTable.setAttribute(fieldstr(CustTable, RecId),int2str(custTable.RecId));
nodeXml.appendChild(nodeTable);
nodeAccount = doc.createElement(fieldstr(CustTable, AccountNum));
nodeAccount.appendChild(doc.createTextNode(custTable.AccountNum));
nodeTable.appendChild(nodeAccount);
nodeName = doc.createElement(fieldstr(CustTable,CustGroup));

This error means that you are trying to use a type as a data contract that is not a valid data contract type.

You only have that two methods?

If you are going to call the class in a menuItem, the class must have the main method.

Are you trying to run your code in a batch process? then look the class tutorial_RunBase that will gave you the basic method you need to overwrite.

Hi,

You need to create an Action MenuItem, you will see the Batch tab in the Dialog, select the batch setup and this will run in a batch.

Remember that you batch services must be running.

Thanks!

I had the similar issue when I put the development comments on top of class declaration. It is silly as comments should not be considered while taking any object. After removing comments it worked fine.
