  • What causes this issue?

    During data processing, one of the analysis processes does not guarantee
    the uniqueness of data records in terms of the key fields they may have.
    One of the DataStore objects, however, has key fields. When data is
    written to DataStore object &V1&, there must only be one data record in
    the key fields for each characteristic combination.

    System Response

    The analysis process is terminated because it is not possible to save
    all the data in DataStore object &V1&.

    How to fix this error?

    Check the definition of the analysis process and make any necessary
    changes. Redefine the analysis process in such a way so that the update
    does not produce duplicate data records. You could ensure against
    duplicate data records by proceeding as follows:
    Check whether all key fields are filled correctly in the field
    assignments on the data flow arrow that enters the DataStore object.
    Insert an aggregation node in front of the DataStore object and
    aggregate the data to match the key fields of the DataStoreobject. In
    the settings for the aggregation node, use the key fields of the
    DataStore object as grouping fields and all other fields as aggregation
    fields.
