<p class=MsoPlainText>Hi all,<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>I have a need for a WF "Program Exit" to
dynamically change the Task Text at runtime. <o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>Currently, if I need to change a task text at runtime, I
create a container element and <o:p></o:p></p>
<p class=MsoPlainText>place it in the WI_TEXT. I then have a background task
determine what the task text should be and<o:p></o:p></p>
<p class=MsoPlainText>pass it in before the Decision step is executed. Kludgy,
but it works and fairly simple to understand. <o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>Now, I want to dynamically change this value using a
Program Exit. <o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>So I added the SAP standard CL_SWF_TST_PE_GETDESCRIPTION
class to a new task and <o:p></o:p></p>
<p class=MsoPlainText>it gets the Desc text and sets a container. Fine. <o:p></o:p></p>
<p class=MsoPlainText>Next, I modified this class to just get/set a Work Item
container. This also works fine. <o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>Now, I tried to get this to change the Task Text with
this new container element but no luck. <o:p></o:p></p>
<p class=MsoPlainText>This changes the container element, but does not change
the Work Item text.<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>Anyone use these WF program exits? <o:p></o:p></p>
<p class=MsoPlainText>Any thoughts, examples, assistance is greatly
appreciated.<o:p></o:p></p>
<p class=MsoPlainText> <o:p></o:p></p>
