Procedure Issue -- As Header Only is not supported?

Hi everyone,

           Currently when I want to run SQL to create procedure  as header only, It will have syntax issue like below?

Could not execute 'CREATE PROCEDURE proheader( p_table_name NVARCHAR(128), p_column_name NVARCHAR(128) ) AS HEADER ONLY'

SAP DBTech JDBC: [257]: sql syntax error: line 4 col 11 (at pos 156)

my SQL is like below:

CREATE PROCEDURE proheader( p_table_name  NVARCHAR(128),

                            p_column_name NVARCHAR(128)

                           )

AS HEADER ONLY ;--##

Does anyone know what happened?  i check the documentation that it is said AS HEADER ONLY is supported in HANA DB.

Thanks.
