10. What is DAX?

11. Data Analysis eXpressions

12. DAX is a function language like
Excel.

13. SUM() COUNT() AVERAGE()

14. CALCULATE()

15. Minority Report

17. Minority Report

18. DAX is Minority Report Programing
- Measures that just work.

19. DAX is Minority Report Programing
- Measures that just work.
DEMO

20. DAX allows you to program what a
metric will do when it is dragged
around.

21. The model handles all the
relationships… but you still need to
worry about it.

22. “The hard part is
what you are not specifying.”

40. Simulate Filtering Demo

41. Exercise - Simulate Filtering

42. Count()
Total Vendors
Total Items

43. Countrows()
Total Transactions

44. Distinctcount()
Vendors that Have Transactions
Items Purchased

45. Max(), Min(), Average()
Avg Unit Price
Max Unit Price
Min Unit Price

46. Divide()
Avg Vendor Spend Amt

Compliance %

57. CALCULATE([measure], <filter1>, <filter2>, … <filterN>)

58. #1 - Pick a cell in the pivot

59. #1 - Pick a cell in the pivot

60. #2 – Got DAX Filters?
Sales 2016 = CALCULATE([Sales],'Calendar'[Year] = 2016)

62. Sales 2016 = CALCULATE([Sales],'Calendar'[Year] = 2016)

63. Sales 2016 = CALCULATE([Sales],'Calendar'[Year] = 2016)

64. Sales 2016 = CALCULATE([Sales],'Calendar'[Year] = 2016)
2016

65. #3 - Picture filters reducing data in
the model
2016

66. #4 - After filtering, apply math

67. #4 - After filtering, apply math

68. #4 - After filtering, apply math

70. 2 Types of Filters:
Simple Filters & Advanced Filters

71. 2 Types of Filters:
Simple Filters & Advanced Filters
CALCULATE([measure], <filter1>, <filter2>, … <filterN>)

72. 2 Types of Filters:
Simple Filters & Advanced Filters
CALCULATE([measure], <filter1>, <filter2>, … <filterN>)

73. Simple Calculate Filter
Sales 2016 = CALCULATE([Sales],'Calendar'[Year] = 2016)
Fixed value

74. Simple Calculate Filter
Sales Customer BCD = CALCULATE([Sales], 'Customer'[Name] = "BCD")
Fixed value

75. Calculate()
On Contract
Off Contract
Optional
Compliance %

76. DAX Level 3

77. Concept – Calculated Columns

78. Demo Total Spend in the item table.

79. SumX() MaxX() AverageX()
Max Item Total Spend
What If Savings

80. MAXX('table',[measure])

81. What If Off was On Amount :=SUMX ('Item',
IF ([Off Contract Avg Unit Price] > [On Contract Avg Unit Pric
e],[Off Contract Qty] * [On Contract Avg Unit Price])
)
What If Savings :=SUMX ( 'Item', [What If Off was On Amou
nt] - [Off Contract] )

82. Exercise
• Calculate()
• On Contract
• Off Contract
• Optional
• Compliance %
• MaxX()
• Max Item Total Spend
