Diagnosis
The transformation List by Data Record is used in node &V1&.When this transformation is executed, the value &V3& occurs multipletimes in the source data for the transformation field &V2&.
When applied to the example in thedocumentation for this node, thiscorresponds to a question having been answered more than once in asurvey. If this data is to be summarized in a data record, only oneanswer can be taken.

System Response
Since it is not clear which data record is the right one in this case,processing of the analysis process is terminated.

Procedure
Check the definition of the analysis process and make any necessarychanges. Define the analysis process appropriately to ensure that noduplicate records arise. You can achieve this by using, for example, anaggregation node in front of the current node to aggregate the data.
