    How to fix this error?

    Additional messages should allow you to find out the reason of the
    failure. If required, contact your system administrator for support.
    Net calculation simulation is organized in the following steps:
    Mapping of the selection criteria to net calculation units
    Net calculation units are the data format used for net calculation
    execution and queries.
    Gross entitlement and gross payment determination
    If required, the entered or changed SSP or SDP data is handled by gross
    entitlement and gross payment determination. As a result, a gross
    payment document (GPD) is created but not stored in the database. The
    GPD is handed over to the next processing step.
    Net calculation execution (simulation only)
    If a new GPD is available, the net calculation is processed for it.
    Query of result
    A query is executed to provide the net calculation result for the
    entered selection criteria. The data is fetched from the database but
    the net calculation result of the prior step is included, if it exists.
    If no entered or changed SSP or SDP data is provided, the result of the
    net calculation simulation displays the database content. This is the
    net calculation result that reflects the current status regarding the
    billing process.
