uwl and substitutions

[Billy Wilde]

Hi All,

substitutions don't work in our uwl.
Most of our users use the uwl for workflow. We have user based substitutions which work fine when using sap gui, but when (active) substitutes try to access the workitems through the uwl they always get this error: 'The item is no longer valid. Please select another item or refresh the item list view.'
They can get around this by using the portal to get to their inbox, and either processing the workitem there, or in the case of srm, reserve the workitem which they will then be able to access in the uwl.
Reserving the workitem seems to fix it, as it puts an entry into table swwuserwi, and then the uwl recognises that the sub is a valid user. 
Has anyone had this before?
We're on 4.7, with ep6.0.
cheers
Bill
