Aurena (Apps 10 UPD 13) Lobby Element Designer weblink - pass current user to customer order

Hello,

I am trying to create a simple Lobby Data Source and Element that will query/retrieve customer orders for the current user (if they are the salesman).

Here is my datasource:

Here is my Element:

page/CustomerOrders/List;path=0.995139193.1811556571.443889496;$filter=SalesmanCode eq #USER_ID#

This is the URL after clicking on link in Aurena

https://ifs10app01.nan.local:49080/main/ifsapplications/web/page/CustomerOrders/List;path=0.995139193.1811556571.443889496;$filter=SalesmanCode%20eq%20%23USER_ID%23

I have also tried Person_ID, as that will bring back results for Business Activites. Does anyone have an idea of what I need to change?

Many thanks in advance.
