  • What causes this issue?

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

    System Response

    The system has checked the transfer rules for the mapping of the key
    fields, and determined that not all the key fields for characteristic
    &V1& are supplied by the DataSource.

    How to fix this error?

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

    Procedure for System Administrators

    The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
