@Anonymous In addition to @FreemanZ response, if you really need a DAX calculated index, it is possible. Can be used in measures as well as DAX calculated columns: The Mythical DAX Index - Microsoft Power BI Community

hi @Anonymous 

there are two options:

1) you may add an index column in Power Query

2) with DAX function:
