When you are trying to clear a warning message in SAP, press enter. That‘s not intuitive. The natural tendency is to continue to press save.
So the sequence of events is:
- change the data
- press the save button
- receive a warning error message
- press enter, and continue to press enter until you are notified that the change has been saved
This will work if it‘s truly a warning message.
