Dear DynamicWeb,
We have an ecommerce solution integrated with Microsoft Dynamics with the standard LiveIntegration plugin, where we see some issues - please see this list:

As a sidenote we do not have any other modification to the integration than this:
[Subscribe(Dynamicweb.Ecommerce.DynamicwebLiveIntegration.Notifications.Order.OnAfterGenerateOrderXml)]
public class OnAfterGenerateOrderXmlNotificationSubscriber : NotificationSubscriber
{
public override void OnNotify(string notification, NotificationArgs args)
{
var myArgs = (Dynamicweb.Ecommerce.DynamicwebLiveIntegration.Notifications.Order.OnAfterGenerateOrderXmlArgs)args;
ClearOrderCurrencyCode(myArgs.Document);
}
static void ClearOrderCurrencyCode(XmlDocument doc)
{
XmlNode currencyNode = doc.SelectSingleNode("//column[@columnName='OrderCurrencyCode']");
//TODO: Move to setting
if (currencyNode != null && currencyNode.InnerText == "DKK")
{
currencyNode.InnerText = string.Empty;
}
}
}
Best regards, Anders
