In the aggregation, there are duplicate char. values for field &1

What causes this issue?

In the aggregation node &V2&, the aggregation relationship NOP (No
Operation) was specified for field &V1&. Aggregation NOP means that
aggregation is not permitted for that particular field.
In this way, you can ensure, for example, that the currency is the same
in all records.
If this case arises, the assessment of the analysis process is
terminated.

System Response

The analysis process is terminated because the data is not allowed to
be summarized for characteristic &V1&.

How to fix this error?

Change the definition of the analysis process. If you want to produce
several records, change the definition of the analysis process by
deleting field &V1& from the list of aggregation fields and adding it
instead to the list of grouping fields.
