• Message number: 016

• Message text: Save your changes first

What causes this issue?

You would like to enter a new delivery schedule. The system, however,
recognizes that you have already entered a new or already existing
delivery schedule in the current transaction.

System Response

The system does not let you enter a second new delivery schedule so
that there are no gaps in the delivery schedule history.

How to fix this error?

You can either change the current delivery schedule or save the
scheduling agreement and then enter a new delivery schedule.
If this message appears in incoming processing for delivery scheduling,
the IDoc finishes in status 51. You must then save the delivery plan
manually in the change mode. After that you can process the IDoc again.
