HANA parameter setting

Hi Colleague,

Currently I'm using one Calculation view CV1 to call another calculation view CV2 as following:

select * FROM "_SYS_BIC"."ags-asord.test/CV2"

WITH PARAMETERS ('placeholder' = ('$$I_CON_NO$$', ':I_CON'));

I_CON_NO is CV1's input parameter, and I_CON is CV2's input parameter.

But it seemed that it will treat :I_CON as a string, not a parameter.

So anybody can advise how to write it correctly?

Thanks,

Doris
