Workflow duration time very high
We have a worklfow created for invoice approval in our NW7 ECC6 ERP system.
Scanning solution from Readsoft scans, verifies and transfers the invoice documents into the ERP system, where then the workflow gets kicked off.
Sometimes a workflow instance consumes much time to complete without throwing any error message.
We activated workflow trace for some hours and loged an instance from start to its end.
that is the last line in the trace before the workflow takes "a break"
then the next line shows:
Synchronization point reached
In the general workflow log we can see the following for "WI update processor" task:
background work item created - time: 09:08:51 AM
background processing started (tRFC entries ......) - time: 09:08:51 AM
work item processing complete - time: 09:33:12 AM
result processing - time: 09:33:14 AM
Our assumption is, that there is a kind of resource bottleneck at the time of background processing.
We checked background processes and there are free processes all the time, also transaction SARFC shows free WPs for RFC.
Have you experienced such a strange behaviour?
I appreciate any hint from your side!
Thanks and regards
