  • What causes this issue?

    As of release EA-FINSERV 200, preliminary costing for loans no longer
    accesses derivation rules that have been defined specifically for
    preliminary costing. The same derivation rules are now used both for
    generating the PA part of the financial object and for preliminary
    costing. You define the derivation rules for the PA part of the finan
    cial object in Customizing (see <DS:SIMG.SIMG_CFJB01JBDDRLOAN>Maintain
    Derivation Strategy</>).
    You can no longer define derivation rules to be used exclusively for
    preliminary costing.

    System Response

    The system outputs an error message when you call preliminary costing if
    derivation rules that are linked to preliminary costing only are found
    in the system after upgrade.

    How to fix this error?

    Run report RJBT_CUST_FOI_LOAN_DERI. This report converts derivation
    rules defined exclusively for preliminary costing into derivation rules
    for the Profitability Analysis (PA) part of the financial object. The
    system inserts the derivation rules to be converted in front of the
    derivation rules for the PA part of the financial object. The derivation
    rules to be converted remain in the same order. Once you have run the
    report, you can continue using preliminary costing.
    Before running the report, check whether the conversion affects the
    derivation result for financial objects and preliminary costing.
