Usage of Stored procedure in Calculation View

Hi Experts,

I have created a non read only procedure in HANA using SQL Console, But when i try to use that in my calculation view, I still get an error that it is read only procedure. I havent written "READS SQL DATA As" in my procedure, So it should be a read/write procedure. Could you please help me with any alternative?

Code :

create procedure "MYSCHEMA".PROCEDURE_TEST()

language sqlscript as

begin

DECLARE tname varchar(50);

     SELECT TABLE_NAME into tname FROM "MYSCHEMA"."TEST_TABLE" WHERE ID ='5';

     execute immediate ('select'||'*'||'from'||tname) ;

END;

In calculation View : 

EXEC 'call "MYSCHEMA".PROCEDURE_TEST();

call "MYSCHEMA"."PROCEDURE_TEST"(varout);

Tried Both, But getting the error  for both syntax as below :

"CALL for non read only procedure/function is not supported in the READ ONLY procedure/function"
