I would like to share with you about a new SAP note which has been released for UWL component:
1886490: UWL does not show the most up-to-date items after logon
This note is about the parameter “Wait duration before calling providers on loading of UWL”, which does not behave properly in case it is set with 0 as its value.
In case you expect UWL to show the most up to date workitems as soon as the user arrives in the UWL without having to wait, then 0 must be informed in this parameter. In case a value other than 0 is defined for it, the information in the UWL Cache for the user will be shown before the time configured is reached, when the retrieval from the providers will be made.
If you have set 0 as the value BUT you still have message “The list of items shown here might be slightly outdated. Waiting for update” showing in the UWL, then you might be running in the issue described on SAP Note 1886490.
