Unable to perform a simple arithmetic operation in CDS View

Hi,

I am unable to perform a simple arithmetic operation in CDS View. I want to add MARC.UMLMC and MARC.TRAME as display it as "Transfer Stock" but i am getting a syntax error(In the highlighted code line) with no help. I have also referred to the below link to check CDS View Syntax option;

CDS View Syntax Options - SAP HANA Developer Guide for SAP HANA Studio - SAP Library

Code Snapshot;

@AbapCatalog.sqlViewName: 'ZDDLS_CDS_TEST'

define view ZDDLS_CDSV_TEST as select from marc

{

matnr as material_no,

( umlmc + trame ) as transfer_stock

}

Please let me know how can I correct the error or what could be the reason for this error.

Regards,

Amit Singh
