Remarks#
This task pairs with the On Material Track In Request task, which listens for the request that this task replies to. It must be executed within the zone created by that task.
MES confirms the operation with any reply and does not read its content. To refuse the operation with a reason, link an Error with a message into reply: MES fails the operation with that message. See Connect IoT - MES Interoperability Scenarios Tutorial.
This task uses a specific structure of context-based data called zone. More information on this topic can be read in the Zones page.
