Workitem not are displayed in Portal UWL

Dear experts.

I am configuring the service of Employee Self-Service-->Leave Request. I am using ehp4

We are using 91000008. This is a copy of the standard 12300111. I created the configurations for Leave Request using t.code PTARQ.

When an employee register the request using ESS-->Leave request, the notifications are in the Business Workplace but not in the UWL:

My configurations are:

1. I define a SAP system.

2. I created a system alias to uniquely indentify the system.

3. I defined exact settings for tecnhical connections.

4. I defined how users are mapped.

5. I tested system connections.

6. I added the new system to UWL configurtion

7. I registered workitem types

Transaction code SWFVISU and registered it

APPLICATION LeaveRequestApprover

DYNPARAM wi_id=${item.externalId}

PACKAGE sap.com/ess~lea

SYSTEM_ALIAS ERP_ED1

APPLICATION LeaveRequest

DYNPARAM wi_id=${item.externalId}

PACKAGE sap.com/ess~lea

I checked SAP Note 779075 - ESS LEA: Termination when WebDynpro applic started from UWL

Thank in advance

Regards
