Default Values with HANA

Hi Guys

In Powerbuilder I have a Datawindow to update a table

On this table some fields has default value at 0

On SQL Server If I run a datawindow.Update and these fields are not valued (Value null) SQL server does not return an error and the App goes on

If I try the same Datawindow on HANA and I do not value a NOT NULL DEFAULT 0 COLUMN, HANA return an error:

"General error;287 cannot insert NULL or update to NULL"

According to you there is some connection parameter to set up in order to avoid this on HANA?

Thanks in advance!
