How to get TaskId's Information using UWL in Webdynpro?

[Former Member]

Hi,

I've to get TaskId's Information using UWL in WebDynpro

from SAP R/3 workflow.

For e.g. Name, Creation Date, Status etc.

I'm able to see property Value in WebDynpro but instead of Property Value I want same Information in WebDynpro without using any Functional Module from R/3

I'm giving the XML file structure which I'm using

I want to display information about the task Id which I'm giving in this configuration.

<?xml version="1.0" encoding="utf-8"?>

<! DOCTYPE UWLConfiguration PUBLIC '-//SAP//UWL1.0//EN' 'uwl_configuration.dtd' [

]>

<UWLConfiguration version="1.0">

<ItemTypes>

<ItemType name="uwl.task.webflow.TS91000129.UWL" connector="WebFlowConnector"

defaultView="Test" executionMode="default" defaultAction="launchWebdynpro">

<ItemTypeCriteria systemId="UWL" externalType="TS91000129" connector="WebFlowConnector"/>

<Actions>

<Action name="launchWebDynPro" handler="SAPWebDynproLauncher"

returnToDetailViewAllowed="yes" launchInNewWindow="yes" launchNewWindowFeatures="width=800,height=600,resizable=yes,scrollbars=yes,status=yes,toolbar=no,menubar=no,location=no,directories=no">

<Properties>

<Property name="WebDynproApplication" value="TEST"/>

<Property name="WebDynproDeployableObject" value="local/TEST1"/>

<Property name="isnewwindow" value="1"/>

<Property name="fruit" value="apple"/>

<Property name="DynamicParameter" value="wi_id=${item.externaId}"/>

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

</Properties>

</Action>

</Actions>

</ItemType>

</ItemTypes>

</UWLConfiguration>

Then in WebDynpro application I'm using this code

String text = WDWebContextAdapter.getWebContextAdapter().getRequestParameter("DynamicParameter");

If I give any other property name I'm able to get in WebDynpro application.

But I tried it for Task Id using Dynamic Parameter I was getting a Blank Value.

Please Help Me.

Hi,

Maybe you can call for example RFC SAP_WAPI_GET_HEADER in the corresponding R/3 system. This gives basic data on the workitem in question.

Thanks for the Help I'm getting the information.

But still I've one question is it possible to get details without using RFC.

I'm rewarding points to you tosolve my problem.

Hi Niharika,

I did the same.

These are the steps you have to do,to retreieve the wi_id.

1. In the application properties add a self-defined parameter called wi_id.

2. Then in the WR code retrieve the wi_id with the help of the WDWebContextAdapater class.

in ur code you have to ask for "wi_id", not for "DynamicParameter".

Job done.

Good luck, Sandhya

Hi Niharika,

I think you have a typo in your code. You can retrieve the work item id by using [code]<Property name="DynamicParameter" value="wi_id=${item.<b>externalId</b>}" />[/code] instead of [code]<Property name="DynamicParameter" value="wi_id=${item.<b>externaId</b>}"/>[/code]

In addition, you can get values from the work item container by extracting them as custom attributes:

[code]<ItemType name="uwl.task.webflow.TS90000001.<system id>" connector="WebFlowConnector" ...>

<ItemTypeCriteria ... />

<CustomAttributes>

<CustomAttributeSource id="WEBFLOW_CONTAINER" objectIdHolder="<element name>" ...>

<Attribute name="<element name>" type="string" displayName="<element description>" />

</CustomAttributeSource>

</CustomAttributes>

<Actions>

<Action name="launchWebDynPro" handler="SAPWebDynproLauncher">

<Properties>

...

<Property name="DynamicParameter" value="<custom param>=${item.<element name>}" />

</Properties>

<Descriptions default="" />

</Action>

</Actions>

</ItemType>[/code]

Hope this helps,

Mikko

Hi,

As far is I know not, because workitems reside in the backend R/3 system. So you have to connect in one way or another.

Hi Igor,

I was doing the same thing..but I was getting only the External Id of that task...

I wantto get other attributes related to that particular task id....like subject,status,creation date....etc.

Thanksfor your help

Hi,

Have you tried getting a parameter called "wi_id" from the Requeststring ? This is how it works for me.

I'm using the UWL on Portal SP15 with PDK.Net and in .Net I can get the id using next line of coding :

Request.Params("wi_id")

Igor
