SNMP Templates : MACRO SQL ERROR - No column name was specified for column 1 of 'ubr1fvjh_exk'.

YM_SW

I'm trying to add a customer property ( Device_Source is as shown below)  in SNMP trap template which is  used in alert action to send the trap to Netcool.

<OID OID="1.3.6.1.4.1.11307.10.36" MIB="SNMPv2-SMI" Name="enterprises.11307.10.36" Value="$${N=SwisEntity;M=CustomProperties.Device_Source}" DataType="4" ValueName="DeviceType" HexValue=""/>

But it appears to be failing with following error.  Have any faced the same please.

MACRO SQL ERROR - No column name was specified for column 1
