We solved the problem.
@Kali: That is not exactly what we wanted to do. We wanted to add the personalization function to an existing view.
@Joshua: Our solution is similar.
First we commented out the coding in the tray-setter that asks if the business function CRM_INF_1 is active.
We commented out the following in grouplinks.htm:
<thtmlb:traySetter personalizationMode = "<%=
lv_pers_enabled %>" />
<%-- switchId = "<%=
cl_crm_sfw_ehp1_switch_check=>co_inf_1 %>" />--%>
After that we added a new component usage on WCC_SRV_HOME without a request on the business function. Finally we addred the view to the view set.
