<DS:DE.SIMRUNID>Simulation period</> &v1& uses a
<DS:DE.BISIMTYPE>simulation type</>, for which the
<DS:DE.CHECKKEYDATE>Check Key Date</> indicator is not set. However, the
<DS:DE.KEYDATE_MSIM>Key Date of Mass Simulation</> is not initial.

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?

This situation can only arise if you use a different simulation type
subsequently in the simulation period, or if you change the simulation
type itself. We recommend that you do not make such changes.
Delete the simulation period and create it again from new.
