Hi Heather
I hope you are keeping well and many thanks for using the SAP Discussion Forums 
.
In relation to the scenario described you mentioned:
- uploaded custom XML as "High" using the "Upload New Configuration" tab in portal. However, the default XML continues to take precedence. You re-uploaded the custom XML, re-registered the system alias and cleared the UWL Cache page.
Now based upon your second response you mentioned making some observations and highlighted the wrong system being selected as a probable cause.
If you continue to encounter the issue kindly let me know here as this would be interesting behavior and might indicate the need to delve a little deeper. Ordinarily as you already know when dealing with custom XML's and the UWL the notion of precedence is indeed affirmed through "High" priority settings followed by a clearing of the UWL Cache. Therefore for this process not to work this may indicate an underlying issue.
- I will await your feedback
Kindly update me as per your findings.
Kind Regards & Talk Soon
