You cannot log on (CUA System assignment missing)

1370 Views

Hi

We are in the middle of CRM upgrade. We upgraded couple of test (CRS) and Dev (CRD) server. We are creating both CRD/CRS in the Solution manager system landscape using tcode SMSY as the satellite servers. Connectivity between satellite server CRD and solution manager server SMP (also in CRD and SMP) has been successfully created.

While checking the Authorization test in Sateliite server (CRD/CRS) for RFC "SM_SMPCLNT050_BACK", we are getting the following error:

"You cannot log on (CUA System assignment missing)"

All other RFC created by SMSY is working fine.

To Fix this problem, i tried to repeat same process again. I was able to delete following RFC's using "clean-up RFC" function of SMSy tcode.

- SM_CRDCRMCLNT050_READ

- SM_CRDCRMCLNT050_TMW

- SM_CRDCRMCLNT050_TRUSTED

and in satellite server (CRD), i deleted following RFC's manually:

- SM_SMPCLNT050_BACK

- SM_SMPCLNT050_TRUSTED

Now, when i checked the RFC destination in SMSY of solution manager server, it is still showing me RFC "SM_SMPCLNT050_BACK". But it is not there in the satellite server as i had deleted it manually. To verify it, I checked table RFCDES in satellite server and "SM_SMPCLNT050_BACK" RFC is not there in table.

I again re-generated RFC's in SMSY of solution manager server, but got the same error ""You cannot log on (CUA System assignment missing)" for SM_SMPCLNT050_BACK.

So we are getting two problem for same process:

- You cannot log on (CUA System assignment missing)

- I deleted RFC " SM_SMPCLNT050_BACK" manually in the satellite server but SMSY still showing it in "Clean up RFC windows".

Not sure if both problems are related to each other. Pls guide to solve these issue's.

Thanks
