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
Solved! Go to Solution.
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,

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,
