Diagnosis
For a key of time-independent master data or time-independent texts,DataSources can transfer to BI several data records in a request. TheDataSource carries information about whether there are potentially anyduplicate records in the request. This information is passed on to thescheduler when new InfoPackages are created.
In this case, duplicate records are ignored in BI by default. Whenmultiple data records are transferred, the last data record of a requestfor a particular key is updated to BI by default. The remaining datarecords for this key in the same request are ignored.
The function that recognizes duplicate data records is attached to thekey for the characteristic. This means that all the key fields forcharacteristic &V1& are supplied by the DataSource.

System Response
The system has checked the transfer rules for the mapping of the keyfields, and determined that not all the key fields for characteristicV1 are supplied by the datasource.

Procedure
As a rule, all the key fields for characteristic &V1& are supplied bythe DataSource. In certain cases, and depending on the application, itcan make sense to provide other rules for the key fields.
