I tried the posting here, https://community.powerbi.com/t5/Desktop/Add-column-where-the-first-duplicate-value-gets-value-1-and... , but it doesnt work.

 

Thank you.

pls try this

Column =
VAR _count=CALCULATE(COUNTROWS('Table'),FILTER('Table','Table'[Index]<EARLIER('Table'[Index])&&'Table'[Invoice No]=EARLIER('Table'[Invoice No])))
return if(ISBLANK(_count),'Table'[Invoice No],'Table'[Invoice No]&"-"&_count)
