Question about displaying handler errors in the webdynpro

    Hello all, Please forgive any EM terminology mixups as I am new to this unique module!

    Here is my scenario, I am in EM WebDynpro and updating the actual dates on a purchase req. The event handler accepts the date I entered and in the background makes a synchronous rfc call to ECC to update the related project with the new date. This rfc call fails because I have the project open and it is locked. This call is synchronous so I get the error right away and I set the return code to 4 and populate an error message that I want passed back to the user in WebDynpro. For some reason the EM system is ignoring this error and returning to the user a successful ‘sent’ message.

    EM WebDynpro –> Purchase Req –> PO Approved Actual Date entered –> synchronous RFC to ECC to update Project –> project locked error returned by ECC –> error message populated in EM –> EM WebDynpro returns as if it was successful

    I have put in breakpoints to ensure I was populating error messages back to EM and I see the details flowing back that are correct, but no details are returned to the actual user. If I go to the Event Handler Overview in the GUI I can find my error message recorded there. Problem is our users will be working from the Web primarily and would not see this message in a normal course of work.

    Is there a config piece that I should be setting to return this error to the users in WebDynpro? This seems like a trivial/standard piece of functionality so I am confused as to why it is not showing up in the dynpro.

    Thank you for any help or ideas and points awarded of course!

      Hello John,

       

      as I understand your right you have an activity which calls ECC. If it is not succesful (e.g. your purchase order is locked) you want that an Error message is also given back on the Web Dynpro.

       

      You can see the error in the log as a log is written for processing an event message. If you also want to see that error message on Web Dynpro you need to consider the following points:

       

      – Make a Multitask Activities with your new activity and as second activity use the method RETRIEVE_MSG. Just call this if your return code is 4.

      – Do the settings as descibed in the help text. You can also have a look on multitask activity PTA10_ID_KNOWN.

       

      Don’t forget to enter a message class under the Event Message Profile.

       

      Hope this helps.

       

      Regards

      Berthold
