Diagnosis
You can set up a value hierarchy to structure your values (for example,the value 'EUROPE' with subordinate values 'FRANCE', 'ITALY', and soon). EUROPE is a value node with subordinate values.
In object dependencies, value nodes represent a value set of severalindividual values. You can use a value node in expressions such as:
COUNTRY IN 'EUROPE'
However, the value you selected is not a value node, because nosubordinate values are maintained.

Procedure
Check your entry for the characteristic value or maintaincharacteristic values as required. If you want to refer to anindividual value, do not use the keyword IN. For example, enter:
COUNTRY = 'FRANCE'
NOT
COUNTRY IN 'FRANCE'
