Thank you

Ok, but you forgot to tell us the most important thing: did you solve your scenario?

Thanks.

Have fun with DAX!

No, i got an error while calculating 2nd formula i.e. 

VAR Suppliers =
    CALCULATETABLE (
        ADDCOLUMNS (
            VALUES ( Trans[Supplier Name] ),
            "SuppliedQty", CALCULATE ( SUM ( Trans[Qty] ) )
        ),
        ALLEXCEPT ( Trans, Trans[Item Code] ),
        Trans[Supplier Price] = MinPrice
    )

It is not working,  showing the below error.

The expression contains multiple columns, but only a single column can be used in a True/False expression that is used as a table filter expression.

Can you please recheck the solution in Power BI, I mean can you provide the solution screenshot.

And one thing i want to tell you, In my case supplier price( I mean one supplier price) will be same for all transactions for that item code

Eg: Supplier A supplied at $1 for the item code 1001 . We may have 1000 transactions with supplier A for the item code 1001, but        he will supply at $1 only.

      Supplier C supplied at $3 for the item code 1001. We may have 2000 transaction with supplier C for the item code 1001, but          he will supply at $3 only.

Thank You

Thank you @AlbertoFerrari

I made a mistake that's  why i got an error, sorry for that.

Now its worked without error but i got blanks in some rows (Almost in 50% rows). Can you Please tell me what could be the reason?

Thank you

Without looking at the data? No way... Likely, there's a bug somewhere in the code, but I would need some test data to find it. If you can share some sample data where the errors spots, then I can take a look at it.

Thank you @AlbertoFerrari

Now its working, I changed formula according to my requirements.

Now i am checking with my report which i have done it in excel. If i found any deviations i will get back to you with the sample data, otherwise i will accept it as a solution.

Once again thank you so much

Hi @Ashish_Mathur, @AlbertoFerrari

Supplier price will be same for all transactions because i was added Average price column. My caluculations will be on average price only. Thedata was very big thats why i was given small data. If we get solution for this sample data thats enough for me.

First it should check for the lowest price supplier, if conflicts then only it should check the quantity.

And the supplier price (Particular supplier price) will same for all the transactions for that particular item

I was not deleted my post, i don't know why it was gone

Here is my original post.

Thank you Mr. Interkoubess, it worked perfectly when suppliers supplied at unique prices. As told by the Ashish_Mathur there could be a chance that different suppliers can supply for the same price, in that case it is not working. It is showing the below error

A table of multiple values was supplied where a single value was expected.

Suppose if one item was supplied at the same price by the different suppliers, then the answer shall be the supplier who supplies more quantity and if the quantity is also same, any one of them is ok for me

Now i am changing the data for better understanding 

Please find the below table

						*Require Column
Transaction ID	Item Code	Supplier Name	Supplier Price	Qty	Item Minimum Price	Minimum Price Supplier
1	1001	A	1	100	1	B
2	1001	A	1	200	1	B

37	1004	V	22	300	19	U
38	1004	W	23	400	19	U

For the item code 1001 the minimum price is 1,

Two suppliers A&B supplied at 1, 

B supplied 350 units but supplied only 300 units , So the answer should be "B" for item code 1001

For the item code 1002 the minimum price is 6,

Only supplier F supplied at 6, So the answer should be "F"  for the item code 1002

For the item code 1003 the minimum price is 12,

Only supplier M supplied at 12, so the answer should be "M" for the item code 1003

For the item code 1004 the minimum price is 19

Two Suppliers S&U supplied at 19,

Both suppliers supplied the same quantity of 400 units, in that case answer shall be S/U, but it should same for all the transactions

Please let me know if clarification needed?

Thanks in advance

I think he removed it. I was answering that post (he published some data with duplicates, that made the problem much more interesting) and the forum told me the message was no longer there. Thus, I replied to the main topic, even if I used data from that deleted message to do some tests.

Have fun with DAX!

Well, that was a nice one!

This works as a calculated column, it is somewhat intricated, but it will return the first supplier based on the quantity sold and the supplier name who sold at the min price:

CheapestSupplier =
VAR MinPrice =
    CALCULATE (
        MIN ( Trans[Supplier Price] ),
        ALLEXCEPT ( Trans, Trans[Item Code] )
    )
VAR Suppliers =
    CALCULATETABLE (
        ADDCOLUMNS (
            VALUES ( Trans[Supplier Name] ),
            "SuppliedQty", CALCULATE ( SUM ( Trans[Qty] ) )
        ),
        ALLEXCEPT ( Trans, Trans[Item Code] ),
        Trans[Supplier Price] = MinPrice
    )
VAR TopSupplier =
    TOPN ( 1, Suppliers, [SuppliedQty], DESC, Trans[Supplier Name], ASC )
RETURN
    CONCATENATEX ( TopSupplier, Trans[Supplier Name], ", " )

Please note that the quantity sold does not depend on the price, supplier A might have sold you something at 200, then some at 300 and the two values will be summed together to determine if he's the best one.

Youc an adapt it to consider only the quantity at the lowest price, or modify the code to compute slightly differnt calculations, the core should remain the same.

Hi,

Can there be a case where the minimum price is the same for the same Item code but supplied by different suppliers.  For e.g. supplier A and C both have a price of 1for item code 101.  If this is a possibility, then what result would you want?  Please clarify.

[Interkoubess]

Hi @Nagarjunav,

Please try this measure with my table named Data:

Test =
LOOKUPVALUE (
    Data[Supplier Name],
    Data[Supplier Price], MIN ( Data[Item Minimum Price] )
)

Please ley us know if you have any observations...
