How do you retrieve full Sales Order data for use in an A2A service?

[Expert]

In an asynchronous A2A integration scenario where full message transfer is necessary. How would you retrieve the latest/complete sales order data before you need to do a change on a specific field since A2A does not provide a read service.

If your sales order processing requires changes on very specific fields, or complex changes - you may want to check the Odata API for this. Otherwise, you can achieve this with an A2A service - to retrieve back the complete information you can use the notification information. The notification provides you back with the full list of fields in the sales order - and you can use the notification information to build your changes based on that.

Additionally, you can register to the business events that are triggered for any change in the sales order, and retrive the respective data that you want to change via the respective odata api.
