SAP update task V2: Average wait time in dispatcher queue

What causes this issue?

All update requests are stored in the appropriate dispatcher queue
untile they can be assigned to a free work process. If this value
triggers an alert, we recommend (if it is not simply a case of a
temporary bottleneck) that you increase the number of update work
processes. You should also take account of SAP Note 39412 (How many
work processes to configure).
