MSS - Problem with IBO_WDA_INBOX

Hi all,

We are implementing the leave request approval with EHP6 and MSS Addon with NWBC.

Everthing is Fine, except the approval in IBO_WDA_INBOX.

I activated the New Standard Workflow and the Workitem (TS2150003) is Shown in Query 'Workitems'.

But if I execute the Workitem the approval wda application doesn't Start. Instead a Message appears

'Workitem Cañons be executed by Business workplace'.

The SWFVISU Customizing is there.

And One additional Question: Is a Maß approval for Workitems possible in WDA-Inbox?

Thanks for your help!

Best regards

Marco
