HDBTABLE definition with default values

Hi,

We are creating tables in HANA with hdbtable.

We need to add default values for the date fields as current date. However, the regular CURRENT_UTCDATE is not recognized as a system variable to be assigned. This works fine when we create a table manually using the CREATE statement but not in HDBTABLE.

Is there some other variable I can use?
