Hi, @hstance
I am glad to help you.
According to your description, you want to why New Table now greyed out and unavailable in Fabric Semantic model?
If I understand you correctly, then you can refer to my solution.
You can check this by following a few steps:
If the data structure in lakehouse has changed, it may affect the use of 'New Table'.
Check if your user permissions or roles in workspace have changed recently. If your permissions have been changed, you may lose the ability to create new DAX tables.
Verify the storage mode of your current model and make sure it allows the creation of DAX tables.
If the above steps still don't solve the problem, please share your procedure and we will do our best to solve the problem you encountered.
I hope my suggestions give you good ideas, if you have any more questions, please clarify in a follow-up reply.
Best Regards,
Fen Ling,
