Data Modelling in PBI for multiple conditional joins
Hi,
I am pretty new to PBI and data modelling. Instead of using SQL views i tried to join the tables directly in PBI and it is working perfectly. But now I have got the below scenario. In Merge I can select the column or multiple columns for joining but how can i define the below highlighted while merging my tables.
From
dbo.IncidentDimvw I
INNER JOIN dbo.WorkItemDimvw WI
ON I.EntityDimKey = WI.EntityDimKey
LEFT OUTER JOIN
dbo.WorkItemCreatedByUserFactvw
ON dbo.WorkItemCreatedByUserFactvw.WorkItemDimKey = WI.WorkItemDimKey
AND WorkItemCreatedByUserFactvw.CreatedDate =
(
Select Max(CreatedDate) from WorkItemCreatedByUserFactvw where WorkItemDimKey = WI.WorkItemDimKey
)

You could get by two merge steps as below:
First merge
Step1:
In Merge function, merge WorkItemDimvw table and WorkItemCreatedByUserFactvw table
Step2:
Expand CreatedDate column and then use Group By to get Max(CreatedDate) for each WorkItemDimKey
Second merge
Now merge WorkItemDimvw table and WorkItemCreatedByUserFactvw table by two conditional
dbo.WorkItemCreatedByUserFactvw.WorkItemDimKey = WI.WorkItemDimKey
and Max(CreatedDate) = WorkItemCreatedByUserFactvw.CreatedDate
