I'm trying to create Sales Order with Group Items, but I want to add an extra item that is not configured by default as Sub-Item of a Group. I add to request: Group Item, extra item and End Of Group Item. But NetSuite fails with message: End Of Group without matching Group item at line and error code: USER_ERROR. I couldn't found any description of this error. But I'm not sure about the NetSuite configuration: Maybe it's an error from some Script....
The same error is not just for extra item, I got it if just specify the Group Item, all sub-items (as configured) and End Of Group Item.
