SM21 - Request (type DIA) cannot be processed



In SM21, I get this error and cannot determine the root cause through SM21 as no help or drill capability exists.

SM51 shows that dialog processes are available as no CPU time is posted against some of them. Where do I look in the system to get a bit more of an insight on this thing?

Thank you in advance for your help,



Here is a copy of the whole SM21 log entry:
