Hello all,
passing on null values to a connector is currently only possible in a sort of indirect manner: You simply leave out that parameter whenever you execute the connector call from within a business object. If you pass on a whole struct to the connector and only want to have certain fields set as null whenever no user input was made, you need to handle that explicitly by setting the value of such fields in the struct as undefined. This will only work however, when the column of your table has its default value set to NULL since the undefined coming from the field of the struct will result in that field being ignored from the JDBC driver alltogether. Looking at your table configuration @anuragkumar you should be fine though.
Regards,
Armin
