Filter Duplicate rows based on a value in the column

[ilyaadna]

I am new to POWERBI and thanks in advance for everyone's help. Here is my problem. I am trying to remove duplicates based on Scrap_Qty value. If Scrap_Qty=1, it shoud keep that row and filter any other row that has same serial_No but Scrap_Qty=0

Here is an example. For HC3078-05, It should keep the top row since Qty_Scrap=1 and then it should compare this serial number with all the other rows and filter out HC3078-05 with Qty_Scrap = 0 (last row in this case).  

If i can do that at "transform data" stage, that will be awesome otherwise even a DAX function will work great. Appreciate the help on this!!

Hi  @ilyaadna ,

In Power Query – Select the yellow label – select only the box that is 1.

Thanks for the input Liu. What you are suggesting will filter out all the Qty_Scrap=0. However, what i want to do is to keep all the ScrapQty=1 and filter out only those ScrapQty=0 rows for which there is a serial_no duplicate with Scrap_Qty=1. Again, appreciate your help

@ilyaadna , Try a new column like

Flag = 

var _cnt = countx(FIlter(Table, Table[Serial No] =earlier(Table[Serial No]) , Table[Serial No])

return

Switch(True() ,

Scrap_Qty in {0,1} , 1,

isblank(_cnt ) ,1 ,

_cnt=1, 1,

0)
