XMLA endpoint not supported for sharepoint connection

[PowerBI_Mallow]

I am having a workspace "A". In this workspace there is a dataset "A" connected to sql datasource, there is another dataset "B" which is connected to both sql datasource & sharepoint. I am able to connect dataset A to some of the client tool like tabular editor. Howere  I am facing the below error as in the attached screenshot when connecting dataset b to tabular ediotr and make changes ,

I have enable XMLA read/write in capacity settings also.

Can anyone helop on this ? Thanks in advance!!

@PowerBI_Mallow , Make sure it is enabled in Tenant Setting and capacity setting too

Also, sometimes it takes 5-10 Min to reflect the same
