Diagnosis
You have specified a date in operand &v3& that is not within thepermissible maintenance period &v1& - &v2&.
The permissible maintenance period results from the view you have chosenfor maintaining facts. For example, if you have chosen a view thatdisplays only the facts for the contract that is currently valid, thenthe permissible maintenance period is also restricted to this validityperiod.

Procedure
If you wish to maintain operand values outside the period &v1& - &v2&,choose a fact maintenance view with a period that contains the date youneed (for example, all facts).
