IBX doesn't work with right UPDATE when applied to an only column

IBX doesn't work with right UPDATE when applied to an only column. For
example: GRANT UPDATE (NAME) ON CONTACTS TO... <ROLL NAME>.  Then, when
applied the method IBDATASET.EDIT a mistake message is discharged: " Cannot
Update. No Update Query)." That is to say, IBDATASET only recognizes
commands UPDATE if the user has access (right) to update the whole table. Is
there as outlining that situation?
