DAX Measures, Calculate, Filter, All

• Sales = SUM(SalesTable[Sales])
• Sales A = CALCULATE([Sales], FILTER(SalesTable, SalesTable[Company]= "A"))
• Share A = [Sales A] / [Sales]
• Filter on A
• Sales All = CALCULATE([Sales], ALL(SalesTable))
• Change: Share A = [Sales A] / [Sales All]
• Whoops, looks like we’re losing too much context (no date context anymore, all context was removed by using ALL).
• Sales All Companies = CALCULATE([Sales], All(SalesTable[Company]))
