Syntax to call a procedure with 2 out parameters

Hi,

I am trying to call a procedure with 2 out variables - a table type and a scalar variable. Signature as below

CREATE PROCEDURE _SYS_BIC.<procedurename>(OUT DOC_TABLE DOC_TABLE, OUT FINAL_RESULT INTEGER) LANGUAGE SQLSCRIPT SQL SECURITY DEFINER DEFAULT SCHEMA ABAP AS  /********* Begin Procedure Script ************/ BEGIN

I am able to call the procedure and get desired output in SQL console with below statement:

CALL "_SYS_BIC"."<procedurename>" (NULL,?);

However, I am not able to find the right syntax needed to call this procedure within another procedure. I tried

declare outvariable INTEGER;

CALL "_SYS_BIC"."<procedurename>"(NULL, :outvariable);

I also tried

declare outvariable INTEGER;

CALL "_SYS_BIC"."<procedurename>"(NULL, outvariable);

Both above statements give syntax error:

Expression cannot be used as an assignment target: NULL

I understand that I can call this procedure by eliminating the OUT DOC_TABLE parameter as I am passing NULL to it anyway. But is there a way to call the procedure as I am able to call if from console?
