Join with Clauses

[Diogo_Dalla]

Hi,

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

For example:

Scrap Table:

Order	Step	Quantity Scrapped	Cost
1234	3	1	37

Order table:

Order	Step	Cost
1000	1	10
1000	2	12
1000	3	15
1000	4	10
1000	5	10

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,

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] ) )
)

If the problem is still not resolved, please provide detailed error information or the expected result you expect. Let me know immediately, looking forward to your reply.

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,

Hi @Diogo_Dalla ,

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

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]))

If the problem is still not resolved, please provide detailed error information or the expected result you expect. Let me know immediately, looking forward to your reply.

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,

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

If the problem is still not resolved, please provide detailed error information or the expected result you expect. Let me know immediately, looking forward to your reply.
