Fungsi iterasi
- Iterasi tiap baris tabel untuk menjalankan sebuah ekspresi
SUMX(<table>, <expression>)
AVERAGEX(<table>, <expression>)
- X berarti eXpression
- Memungkinkan perhitungan lanjut per baris
Fungsi iterasi: SUMX()
Contoh kolom terhitung
Cost = Fact_Orders[Sales] - Fact_Orders[Profit]
Total Costs = SUM(Fact_Orders[Cost])
| Sales | Profit | Cost |
|---|---|---|
| $77.88 | $3.89 | $73.99 |
| $22.72 | $10.22 | $12.50 |
| ... | ... | ... |
| Total Costs |
|---|
| $2,569 |
Fungsi iterasi: SUMX()
Contoh kolom terhitung
Cost = Fact_Orders[Sales] - Fact_Orders[Profit]
Total Costs = SUM(Fact_Orders[Cost])
| Sales | Profit | Cost |
|---|---|---|
| $77.88 | $3.89 | $73.99 |
| $22.72 | $10.22 | $12.50 |
| ... | ... | ... |
| Total Costs |
|---|
| $2,569 |
Contoh fungsi iterasi
Total Costs SUMX =
SUMX(Fact_Orders,
Fact_Orders[Sales] - Fact_Orders[Profit])
| Total Costs SUMX |
|---|
| $2,569 |
Menyaring fungsi iterasi
- Gunakan fungsi filter, seperti FILTER(), untuk mengembalikan tabel terfilter
SUMX(
FILTER(
<table>,
<filter>),
<expression>)
Total Costs East SUMX =
SUMX(
FILTER(
Fact_Orders,
Fact_Orders[Region] = "East"),
Fact_Orders[Sales] - Fact_Orders[Profit])

Fungsi iterasi: RANKX()
RANKX(
<table>,
<expression>)
- Peringkatkan region berdasarkan total biaya
Total Costs RANKX =
RANKX(
ALL(Dim_Sales[Region]),
[Total Costs])
- Gunakan
ALL()untuk mengevaluasi semua baris dari tabel dimensi
