ia/<customerID>/<location>/<AssetID>/addOrder


ia.<customerID>.<location>.<AssetID>.addOrder

Usage

A message is sent here each time a new order is added.

Content

key	data type	description
`product_id`	`string`	current product name
`order_id`	`string`	current order name
`target_units`	`int64`	amount of units to be produced

The product needs to be added before adding the order. Otherwise, this message will be discarded
One order is always specific to that asset and can, by definition, not be used across machines. For this case one would need to create one order and product for each asset (reason: one product might go through multiple machines, but might have different target durations or even target units, e.g. one big 100m batch get split up into multiple pieces)

JSON

Examples

One order was started for 100 units of product “test”:

{
  "product_id":"test",
  "order_id":"test_order",
  "target_units":100
}
