<P><FONT SIZE=3D2>Thanks for the reply Stephen (and Martin).</FONT>
</P>
<P><FONT SIZE=3D2>Stephen,</FONT>
<BR><FONT SIZE=3D2>I'm not real conversant with the difference between =
asynchronous/synchronous tasks and terminating events, so any more =
detail you can add is greatly appreciated. Would I have to add =
any additional Workflow steps after the change ECR task in regards to =
your solution below?</FONT></P>
<P><FONT SIZE=3D2>p.s. A change document is created when I enter the =
effectivity on the ECR.</FONT>

<P><FONT SIZE=3D2>The update lag is a problem that occurs frequently =
with workflow. I had the</FONT>
<BR><FONT SIZE=3D2>same issue with updates in MM a while back; I solved =
it by convincing SAP to</FONT>
<BR><FONT SIZE=3D2>change the timing of the workflow event =
creation.</FONT>
<BR><FONT SIZE=3D2>In your case, that's not an option.</FONT>
<BR><FONT SIZE=3D2>The safest thing would be to establish an event =
creation, with using</FONT>
<BR><FONT SIZE=3D2>SWC_EVENT_CREATE in a user exit or using an existing =
event creation (change</FONT>
<BR><FONT SIZE=3D2>document etc.). Then make the user decision task =
asynchronous, and use that</FONT>
<BR><FONT SIZE=3D2>event as a terminating event. That would fire =
(assuming the event creation</FONT>
<BR><FONT SIZE=3D2>in the application is late enough in the update =
task) after the change is</FONT>
<BR><FONT SIZE=3D2>registered in the database, as opposed to when the =
dialog session finished</FONT>
<BR><FONT SIZE=3D2>(i.e. the user hits save and the standard task =
ends).</FONT>
<BR><FONT SIZE=3D2>Alternatively, use function module =
"RZL_SLEEP" to make the method pause for</FONT>
<BR><FONT SIZE=3D2>a little while and then continue. Better than the =
continuous selects for</FONT>
<BR><FONT SIZE=3D2>performance.</FONT>

<P><FONT SIZE=3D2>We've got a point in our Workflow where a work item =
is sent to a user (a SAP</FONT>
<BR><FONT SIZE=3D2>method calls a tran in change mode). We're =
assuming that the user will</FONT>
<BR><FONT SIZE=3D2>enter some data, but we'd like to add validation to =
make sure that he/she</FONT>
<BR><FONT SIZE=3D2>does (otherwise, it causes errors later in the =
process).</FONT>
</P>
<P><FONT SIZE=3D2>My idea was to create a custom method by copying the =
SAP method and then add</FONT>
<BR><FONT SIZE=3D2>some validation code. This validation code =
would catch the invalid data,</FONT>
<BR><FONT SIZE=3D2>display an error message and then do an =
"exit_cancelled" to keep the work</FONT>
<BR><FONT SIZE=3D2>item in the user's queue (in process). =
However, after doing this there</FONT>
<BR><FONT SIZE=3D2>seems to be a update delay in Workflow - even after =
entering the required</FONT>
<BR><FONT SIZE=3D2>data, Workflow doesn't recognize it. The only =
ways I can get around the</FONT>
<BR><FONT SIZE=3D2>problem: 1) Keep re-executing the work item until =
Workflow sees the updated</FONT>
<BR><FONT SIZE=3D2>data; or 2) Put in a high numbered "do =
loop" to give Workflow a chance to</FONT>
<BR><FONT SIZE=3D2>get the updated data within the method (I do not =
like this due to</FONT>
<BR><FONT SIZE=3D2>performance reasons).</FONT>
</P>
<P><FONT SIZE=3D2>I've attached the code for the method (with the =
"do loop"), which brings up</FONT>
<BR><FONT SIZE=3D2>an Engineering Change Request in change mode and =
verifies that an</FONT>
<BR><FONT SIZE=3D2>effectivity date has been entered. I've noted =
the original lines from the</FONT>
<BR><FONT SIZE=3D2>SAP method with "SAP". If anyone has =
any suggestions on how to get around</FONT>
<BR><FONT SIZE=3D2>this update delay, I'd appreciate it.</FONT>
