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