data format help for using excel file in Power Bi

[Dingarbell]

Hi All

Newbie here.

I have a spreadsheet logging an asset collection project with the sites as the UID and date column headers with assets collected per week. This sheet links to another with the specific site data (size, people, location etc)

When I import to Bi I want to have the structure to use the 'Time Intelligence' function.

I know the data is not built correctly but cannot see how to do it (cannot see the wood for the trees).

Any help would be very much appreciated.

I cannot install mini sheet on this laptop so have added an image)

PS I have tried the unpivot in power query but this makes duplicates of the site id which Power Bi does not like

which Power Bi does not like

What exactly does that mean?
