Please first let us know if you have done the configuration as per
the Note 779075, Please do this and re register the work items and
let us know.
Make
Check the configuration of SAP_WebDynpro_XSS
Here is the help documentation:
http://help.sap.com/saphelp_nw70/helpdata/en/92
/a88931f2dd4631b9e8d530697d89c9/content.htm
in regards to this parameter.
IF the LeaveRequestApprover application is deployed on the SAP_Local
System, you needed the system alias of SAP_LocalSystem in the
Webdynpro Launch System value.  With this setting when the user
manager clicks on the item, it will work fine.
the system SAP_Webdynrpo_XSS should have maintained the WAS properties
with the port of the portal. This is for normal working for
Leave request
"Mapping Logical Systems" in the following documentation:
http://help.sap.com/SAPHELP_NW04S/helpdata/EN/2a/7a754297fdd142e10000000
a1550b0/content.htm
and the "sap-wd-arfc-useSys" bullet point in the following
documentation:
http://help.sap.com/saphelp_sm32/helpdata/en/f4/651741f163f023e10000000a
155106/content.htm
See in bold where it mentions that "The prerequisite for this is that,
in addition to the default JCo connections, you created the new logical
system name with the Web Dynpro Content Administrator and configured it
for the required SAP system." Meaning that there needs to be a JCO
Connection for "SAP_R3_SelfServiceGenerics_MetaData" since these are
the default JCo connections. In this case I kindly ask that you create
the default metadata and model JCO connections for
SAP_R3_SelfServiceGenerics and see if that resolves the issue.
