Default: False
Range: True or False

This parameter forces all MISER dates, including keys, to have the DAOPT_Nulls_Allowed bit (value 1) in the da_options column of the DATAITEMS client control table. This parameter should only be set to True if you are using a MISER database. Only one MISER date is allowed as a key. The Client generates custom-stored procedures that handle the cases where the MISER date that is part of the index is NULL.
