How to create an array and loop in DAX

[Anonymous]

I have a large amount of data with a lot of different work centers, but I want to calculate workcenter1(good parts/total parts) * workcenter2(good parts/total parts) * ... but only for a certain list of workcenter numbers. Is there a way to create the list of work centers in DAX or do I need to create a new column with M to create that list?

This is a mishmash of the code that is working and what I would like to do with it:

array BR41 = {"670205","670206","670302","670502","670902","670904","671002","671202"};
float RolledYield = 1;

for(int i=0;i<=7;i++)
{
string LoopedWorkcenterNumber = BR41[i];
float RolledYield = RolledYield *

// DAX code I have been using for calculating the filtered yield data
DIVIDE( CALCULATE( SUM(DWS_ConfPassAndScrap[PassQuantity]),FILTER(ALL(DWS_ConfPassAndScrap[Workcenternumber]),DWS_ConfPassAndScrap[Workcenter]= LoopedWorkcenterNumber)),
CALCULATE(SUM(DWS_ConfPassAndScrap[PassQuantity]),FILTER(ALL(DWS_ConfPassAndScrap[Workcenter]),DWS_ConfPassAndScrap[Workcenter]=LoopedWorkcenterNumber))
+CALCULATE(SUM(DWS_ConfPassAndScrap[ScrapQuantity]),FILTER(ALL(DWS_ConfPassAndScrap[Workcenter]),DWS_ConfPassAndScrap[Workcenter]=LoopedWorkcenterNumber)))

}

Hi,

I would recommend using PRODUCTX function:

test data:
Here the goal is to have your logic applied for cost centers A,B and D. The result would be (1/2)*(2/2)*(1/2)

Here is the dax:

Measure 22 =

var _workcenters = {"A","B","D"}

RETURN

PRODUCTX(

ADDCOLUMNS(

SUMMARIZE(FILTER('Table (31)','Table (31)'[Workcenter] in _workcenters),'Table (31)'[Workcenter]),"good/all",

CALCULATE(COUNT('Table (31)'[ID]),'Table (31)'[Goodpart]=1)/

CALCULATE(COUNT('Table (31)'[ID])))

,[good/all])


End result:

Hi @Anonymous 

not sire if I fully understand the requirement however please try

Measure1 =
PRODUCTX (
TREATAS (
{
"670205",
"670206",
"670302",
"670502",
"670902",
"670904",
"671002",
"671202"
},
DWS_ConfPassAndScrap[Workcenter]
),
CALCULATE (
DIVIDE (
SUM ( DWS_ConfPassAndScrap[PassQuantity] ),
SUM ( DWS_ConfPassAndScrap[PassQuantity] )
+ SUM ( DWS_ConfPassAndScrap[ScrapQuantity] )
)
)
)
