Travel request approval gives ERROR as : Value null of URL parameter SAP_FITV_PERSNO has the wrong type.

Hi All,

We are using portal 7.4 and  r/3  Ecc 6.0 ehp7.

We have create a customized workflow task TS90000026 to create  the travel request  (similar to std task TS20000118).

Workflow is working ok and the Manager receives the work-item to approve the travel request , in UWL in SAP portal.

But, when we click on the work item in portal uwl ,  it is showing following error:

Value null of URL parameter SAP_FITV_PERSNO has the wrong type.

We followed the note 1076144  and uploaded the  zip file given in the note, to portal using " upload new configuration" option.

<!-- Approve Travel Request -->

     <Property name="System" value="SAP_ECC_HumanResources"/>

     <Property name="SAP_FITV_TRIPCMP" value="R"/><!-- Display Travel Request -->

     <Property name="display_order_priority" value="10"/><!-- Shift to left side -->

     </Properties>

    </Action>

If we hard code the Trip number  and persno   , then it successfully displays  a PDF form , when  a manager clicks on the  workitem in uwl inbox.

please suggest a way to sort out this,  without hardcoding the trip no and persno.

BR,
