Customer Order Error Message - The Customer Order record has already been changed. Please refresh the record and reenter your changes

Hi @johnw66,

The error exactly describes what might actually have happened while the user had a quick 5 minute chat with the supervisor.
During this 5 minutes,
1. Another user might have changed the exact Customer Order Line record or,
2. Another user might have triggered a process which would have changed the exact Customer Order Line record or,
3. A background job might have executed and changed the exact Customer Order Line record or,
4. Any other reason where the "rowversion" column of the "customer_order_line_tab" table for the exact Customer Order Line record might have changed.

Technically, the Modify__ procedure is executed when the data is edited and is eligible for an update.
For CustomerOrderLine LU, the following procedure gets executed,

In CustomerOrderLine LU, objversion_ = to_char(rowversion,'YYYYMMDDHH24MISS') holds the timestamp where the record was last modified and this serves the purpose of a locking mechanism as well.
However, there are other implementations for objversion.

You can read more about the Client Interaction mechanisms for further technical understanding.

Cheers !
