    System Response

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

    How to fix this error?

    If you remove all field selections from the list of key fields in the
    error stack on the <LS>Extraction</> tab page, the DTP uses a processing
    type with better performance. The system either processes more steps in
    parallel mode or continues processing the data using serial processing,
    but creates several small data packages to reduce the load on the ABAP
    runtime environment.
    Make sure that the semantic grouping is not a prerequisite for one of
    the DTP transformations before you decide not to build any semantic
    groups.
    <ZH>Note:</>
    If at least one of the transformations requires the data packages to
    contain semantically closed groups, do <ZH>not</> remove the selections.
    Processing in parallel modes is also influenced by various other
    factors, especially the <LS>Parallel Extraction</> field on the <LS>
    Extraction</> tab of the DTP. If the system is supposed to use the
    processing type <ZK>Parallel Extraction and Processing</> and the field
    <LS>parallel extraction</> is <ZH>not</> selected for the DTP, then you
    need to select the field again. For more information on the dependencies
    between the field and the processing type, read the documentation about
    the <DS:DE.RSBKPARALLELEXTR>Parallel Extraction</> field.

    Read the documentation under <ZK>Performance Tips for Data Transfer
    Processes</> in the SAP library.
