Lookup value from table_2 and sum it [DAX]

[Anonymous]

Hi, 

my target is to sum the values from table_1  and insert them into table_2.

How can I do that with DAX? 

Example is shown below:

I wanted to add an easier solution if others are looking for a solution to the same issue.  The steps are listed based on the example provied (i.e. Table 1 and Table 2 in the screen shot).

1. Under the Model View make sure there is a link between Table 1 and Table 2
   1. In this case it would be Table 1.Name No = Table 2.Name No
   2. 
2. In Table 2 create a new measure using the SUM dax

Here is a link to an example workbook with the Table 1 and Table 2 data set for reference

Hi,  @Anonymous 

You need to create a summarize table first (calcualted table)

Tab = SUMMARIZE(Table1,Table1[Name No],Table1[Name],"Cost",SUM(Table1[Costs]))

Tehn using lookupvalue to create a calculated column.

C_Costs = LOOKUPVALUE(Tab[Cost],Tab[Name No],Table2[Name No],Tab[Name],Table2[Name])

@Anonymous you should create a table for name dimension with unique values for the name and set relationship with both the tables, it will be one to many relationships, in visual, use name information from this new table and rest of the columns from the respective table. This is the right way to do this. Read this post
