Could you please help me with the solution to fetch the field "output/outputScript" in the nms:delivery schema. I need to mass update on the value present in that field
I do not think you would be able to mass update this field from the nms:delivery schema
It would need a bit of scripting to access and update this field in the delivery. (delivery.output.outputScript)
Also, this field is of the TYPE CDATA, so you need to bear the rules in mind while updating the field using a script.
