GRC AC 10 SP4- workflow user confusion? Message no. GRFNMW223

I configured GRC AC 10 SP4 workflow using the document "AC 10.0 Pre-Implementatio From Post-Installation to First Access Request.pdf". And using the default BC-Sets.

I can create an access request. But it will never find/assign an approver.

Something strange is also happening:

When I do search the created request and click on Administration (currently logged as user BHT), I get the following messages:

User '&FF_CNTLR&' has no authorization for process '&SAP_GRAC_ACCESS_REQUEST&' administration Display Help

User 'SAP_GRAC_ACCESS_REQUEST' has no authorization for process 'FF_CNTLR' administration

The User FF_CNTLR is supposed to be the manager who should approve this request. He has the role SAP_GRAC_ACCESS_APPROVER assigned.

Now, in order to be able to administer the request that I created as BHT (with Manager FF_CNTLR), I have to assign to the Manager FF_CNTLR the role for Workflow administration. Only then will the screen open the request- as it should.

It looks like the system is doing some confusion between the two users.

Earlier, I also managed to create a request, while beeing logged as BHT, and having entered FF_CNTLR as manager, then the user I requested the change for was suddenly not any more BHT, but FF_CNTLR. I then changed the request from Self to Other, and finally saved it. The result: A request which requestor FF_CNTLR (altough I did all steps while beeing logged as BHT) - I guess there is also a bug - or it is the same problem.

But for the time beeing - I would just be happy if any approver would be found.

Does anybody have an idea??
