Problem with SD workflow- update task list

Puhr erstellt 23 Feb. 2012 17:14

In Sharepoint 2010, we had built a document library and connected a SD list workflow to it starting on creation or change of a document, with the purpose of its approval in seven stages.
The workflow evaluates a document's metadata and invokes the MS prebuilt approval function, which itself creates an approval entry in the task list.
Users complained that the entries of the task list would not show some helpful information about the document to be approved.
So we introduced a further SD list workflow that, on creation of an entry in the task list, is fetching some metadata of the document to be approved and exposing it to the user by some extra columns of the task list.
However, it showed up that, by about 15% of cases, these extra data could not have been added by the workflow to the entry of the task list.
Although the logging of the task list workflow did not show errors in these cases, the basic workflow complained that a task entry could not have been modified after its creation, an a rollback of the task entry has been performed.
Our first idea was on access right settings; but even when giving administration rights to the involved for library and list, the behavior did not change.
Also some playing around with "wait for one minit" did not solve the point. Anybody there having an idea on that behavior? Thank you in advance.
