Hi Team,
I have created a function to load the Exchange rates currency based on the list of dates and to store them.
This works fine in the Power Query, but when i click apply and close i get an error message which is
"Failed to save modifications to the server. Error returned: 'Expression in partition 'n/a' in table 'n/a' references an unknown entity. '."
I am attaching the PBIX file, can anyone please help me to solve this issue ?
Regards

Hi @ncbshiva ,
It seems the issue was caused by enable the preview feature "Store datasets using enhanced metadata format.", and it does not yet support dynamic datasources( the source changes depending on a parameter, function input, or volatile function). The related team is working on fixing the problem. The current workaround is disable this feature and re-create the report with new file...
You can review the contents in the following links for more details...
