I have a problem regarding creating a process instance within the business process flow (bpf) of BPC10. I did create the bpf process similar to the following howto: http://bptools.blogspot.de/2011/11/bpfs-in-bpc-10.html#!/2011/11/bpfs-in-bpc-10.html
It worked like a charm until picture 14 (where I have to choose the context, here time). After selecting a time and clicking on next I get the following error:
Proof of existence of process failed. Internal server failure.
(Sorry for German screenshot in attached file)
I tried to figure out if there is something wrong with the BPC_SERVICE user, but this user has SAP_ALL.
Has anybody a hint for me what to do? Had anybody allready have this issue? Any help would be fine.
