Join with Clauses

Hi,

I am looking for a way to merge two tables adding some clauses to the join.

 

For example:

Scrap Table:

 

OrderStepQuantity ScrappedCost
12343137

 

Order table:

Order Step Cost
1000110
1000212
1000315
1000410
1000510

 

The COST column from the Scrap table is the sum of all Cost column from Order table which step column is <= step column from scrap table.

 

Using SQL it would be more or less like below:

 

Select Scrap.order, Scrap.step , Scrap.QuantityScrapped , Sum(Order.Cost)

From Scrap Join Order

ON Scrap.order = Order.order

AND Order.step <= Scrap.Step

Hi @Diogo_Dalla ,

 

Please try the following measure or custom column(PQ).

 

Measure:

SumCost = 
SUMX (
    SUMMARIZE (
        Scrap,
        Scrap[Order],
        "_sum",
            CALCULATE (
                SUM ( 'Order'[Cost] ),
                FILTER (
                    'Order',
                    'Order'[Step] <= MAX ( Scrap[Step] )
                        && 'Order'[Order] = MAX ( 'Scrap'[Order] )
                )
            )
    ),
    [_sum]
)

PQ Column:

JoinOrderCost =
let 
   myfunction = (CurrentOrder, CurrentStep) => 
     let 
       SelectRows = Table.SelectRows(Order, each [Order] = CurrentOrder and [Step] <= CurrentStep) 
     in 
       SelectRows,
   Data = List.Sum( myfunction([Order],[Step])[Cost])
in 
   Data

Hi,

Would you be OK with a DAX solution?

Hi @Diogo_Dalla ,

 

Please try the following measure:

 

Cost = 
CALCULATE (
    SUM ( 'Order'[Cost] ),
    FILTER ( 'Order', 'Order'[Step] <= MAX ( Scrap[Step] ) )
)

Hi,

THank you for your reply.

 

I checked the model that you sent, but I didn't find where you have added the DAX Code.

 

Have you merged the two tables?

 

Thank you,

Diogo Dalla 

Hi @Diogo_Dalla ,

 

I did not merge the two tables, I simply created a measure as shown below.

 

vkkfmsft_0-1651654033939.png

 

Or try to create a custom column in Power Query to get the data from the Order table and extend it.

 

= Table.SelectRows(Order, each ([Step] <= #"Changed Type"{0}[Step]))

Hi,

 

I think that it is almost there.

 

Doing the models that you shared I found the following:

*  Model1 - The DAX code below is not filtering by Order.

FILTER ( 'Order', 'Order'[Step] <= MAX ( Scrap[Step] ) )

 

I added the following code

Cost = 
CALCULATE (
    SUM ( 'Order'[Cost] ),
    FILTER ( 'Order', 'Order'[Step] <= MAX ( Scrap[Step] ) && 'order'[order] = Max(Scrap[order]) )
)

 

But it will bring the Max Scrap.Step and the Max Scrap.order

 

I was able to do it in Excel with power query this way:

SELECT  `'SCRAP$'`.order
 , `'SCRAPa$'`.Step
 , `'SCRAP$'`.Quantity
 , (SELECT SUM(`'ORDER$'`.Cost) FROM `'ORDER$'` `'ORDER$'`
    WHERE `'ORDER$'`.order = `'SCRAP$'`.Order
    and `'ORDER$'`.Step <= `'Scrap$'`.Sterp)
FROM  `'SCRAP$'` `'SCRAP$'`

It merged the two queries in one bringing the total cost from Order table.

 

* Model2 - Will not bring the sum of the costs from order table.

 

 

Thank you,

Diogo Dalla
