DAX NATURALINNERJOIN

My code:

Resource Allocations =
VAR AssignedCapacityWeighted =
                            SELECTCOLUMNS(
                                SUMMARIZECOLUMNS(
                                    'Project Resources'[ResourceId],
                                    'Project Resources',
                                    "Assigned Capacity Weighted",
                                    SUMX('Project Resources', ((DATEDIFF('Project Resources'[Assigned Start Date], 'Project Resources'[Assigned End Date], DAY)) * 'Project Resources'[Assigned Capacity]) / 365.0)),
                                "Id", 'Project Resources'[ResourceId],
                                "Assigned Capacity Weighted", [Assigned Capacity Weighted]
                            )
VAR ChapterTeamsFullName =
                            SUMMARIZECOLUMNS(
                            'Teams (People)'[Id],
                            'Teams (People)'[Chapter],
                            'Teams (People)'[Team],
                            'Teams (People)'[Full Name])
VAR ResourceAllocationParts =
                            NATURALINNERJOIN(ChapterTeamsFullName, AssignedCapacityWeighted)
RETURN ResourceAllocationParts
 
No common join columns detected... why doesn't it know that ResourceId renamed to Id is the same as Id from the two tables I created? What do I need to do to make it understand this. In my existing models relationships have already been created.

  • NATURALINNERJOIN as per documentation

    Columns being joined on must have the same data type in both tables.
    
    Only columns from the same source table (have the same lineage) are joined on. For example, Products[ProductID], WebSales[ProductdID], StoreSales[ProductdID] with many-to-one relationships between WebSales and StoreSales and the Products table based on the ProductID column, WebSales and StoreSales tables are joined on [ProductID].

    Refer how to use : https://www.youtube.com/watch?v=mcQ_ZmuWvDs&vl=en

     

    there is a costly option

    filter(crossjoin(table1,table2), Table1[A]=Table2[B])

     

    Try in edit query

      Ok, So I made it a step further... almost what I need, code below:

       

      Resource Allocations =
      VAR AssignedCapacityWeighted =
                                  SELECTCOLUMNS(
                                      SUMMARIZECOLUMNS(
                                          'Project Resources'[ResourceId], 'Project Resources'[Assigned End Date].[Year], 'Project Resources',
                                          "Assigned Capacity Weighted", SUM('Project Resources'[Assigned Capacity Weighted]), "Year", MIN('Project Resources'[Assigned End Date].[Year])
                                      ),
                                      "ResourceId", 'Project Resources'[ResourceId] & " ",
                                      "Assigned Capacity Weighted", [Assigned Capacity Weighted], "Year", [Year]
                                  )
      VAR ChapterTeamsFullName =
                                  SELECTCOLUMNS('Teams (People)', "Id", 'Teams (People)'[Id],
                                  "ResourceId", 'Teams (People)'[Id] & " ",
                                  "Chapter", 'Teams (People)'[Chapter],
                                  "Team", 'Teams (People)'[Team],
                                  "Full Name", 'Teams (People)'[Full Name])
      VAR ResourceAllocationParts =
                                  NATURALLEFTOUTERJOIN(ChapterTeamsFullName, AssignedCapacityWeighted)
      RETURN ResourceAllocationParts
       
      Output:
       
      Expecting a single record with Assigned Weighted Capacity = 95%. What am I missing? If I don't group by Year then it works perfectly.

      Not a complete answer, but it was enough to get me moving in the right direction.
