Hi Christophe,
Thanks for your reply.
I can reprocess the Queues but I get the same error on a SYSFAIL queue.
Some of the Queues are orders, but others are WorkForce Updates which I cannot replicate.
Problem I believe is that each Queue with a problem is related to a User ID that was either locked or deleted, and I need to find a way to reprocess them with a generic User ID or to avoid that validation on the user.
On the past we used to ask our Security guy to temporaly unlock those users for us to process the Queue, but it would seem that now that is not possible due to Security Measures.
