Classification node not found at level...

 
 
Error:
Classification node '{0}' not found at level {1}
 
Explanation:
The own classification consists of a maximum of 4 layers.
When importing the own classification, all 4 layers must be filled in.
The level IDs may not be changed or moved.
If they are changed, this error message may appear.
 
Solution:
Create a new export of the own classification and make the changes without changing the Level-Id's.
