SCP API request id field name

SCP API request id field name

I am using the supplied java scripts to create tickets in ServiceDesk Plus from SupportCenter Plus.

This is working ok but I am also trying to include the SCP 'Request Id' in the parameters passed to SDP.

I have created an additional field in SDP called SCP_ID and am using the following update to the SDP.xml:

<param>
<name>SCP_ID</name>
<value>$id</value>
</param>

This does not pass a value to SDP.  
I have tried using $Priority as the value for example to test the functionality and this works OK as does a 'Fixed value' eg 'idvalue'

I have also tried $ID, $RequestID, $woid etc but no value is being passed.

The API documentation indicates that the field name for the request id is 'id' -- Can anyone assist please.
