We have this same issue with eRx not populating in the RX area. I have called both WINOMS and Carestream and was told until we upgrade to the next WINOMS version, we will continue to have this issue. I was also told that if a pharmacy has an "&" in their name you will get this error message. "Failed to save the prescription data back to your PMS. Return code [-1] Failed to find patient or write patient clinicalID." We do get this message with a particular pharmacy with & in their name -everytime!!!! But we also get this error message at other times when their name does not contain &. EXTREMELY frustrating and seems like this could be an easy fix.
