In the past we had serious issues in adjusting notes which have manual activities. After the adjustment in SPAU they still appear in SNOTE with a wrong status (‘Obsolete version Implemented’).
The workaround until now was to deimplement the notes in SNOTE. This was a pseudo-deimplementation which had to be done to confirm the cancellation of manual activities.
This bug has been fixed and rolled out with note #2077553. Please proceed as described in that note to avoid that error in the future.
