Diagnosis
You want to change or delete an option rate method from &V4& &V3&. Thischange affects a time period for which the option rates originate fromyour legacy data transfer.

System Response
For option rates stemming from the legacy data transfer, the system
cannot automatically check if the option rates were already used forinput tax distribution. In addition, it is not possible to ensure thatthe same value results when the option rate is calculated again withoutany change to the option rate method. Therefore, the system does notallow you, when making changes in dialog mode, to delete option ratesthat were transferred during legacy data transfer.

Procedure
If the legacy data transfer was incorrect, then delete the resultingoption rates using the legacy data transfer program. Then correct theoption rate methods on the master data, and have the system recalculatethe legacy option rates.
If the change is not supposed to take effect until after &V2&, then itdoes not involve any transferred legacy option rates. In this case,proceed as follows:

• If you want to change the data of the option rate method, then set the
valid-to date for that row to a value after &V2&. Then insert a new rowwith the changed data and a valid-from date after &V2&.

• If you want to delete the option rate method, then set the valid-to date
of the current row to a value after &V2& (to the day, after which theoption rate method should no longer be valid).
