Problem with single order staging in EWM 9.2

Dear experts,

i did all configurations like it´s said in the documentation advanced production integration (92 pages). But when i activate the business configuration set /SCWM/PMR_SINGLE_ORDER i receive warnings.

I followed the guide and now i am trying to create PMRs. I also set the configurations in transaction /SCWM/PSASTAGE, where i choose the single order staging method. Before i choose the single order staging method my PMRs were created without problems, but now the inbound queue of my EWM-System catches the requests...

Any ideas what could solve the problem and let me create PMRs with staging method single order staging ?

Best regards

Eike
