missing data in column

[maurcoll]

Good Afternoon

I have a table which contains data like the below. Some of the completed by fields are blank and i need to fill them in. If the order number is the same then it will be completed by the same person.

Date	Order Number	Review Type	Completed by
31/01/2023	123	First	2589
31/01/2023	123	Second
31/01/2023	234	First	1116
31/01/2023	234	Second	1116

In the above example i need a way of copying the completed by into the row below.

and  try this

Table.Group(#"Changed Type", {"Order Number"}, {{"Count", each Table.FillDown(_,{"Completed by"})}})

watch my video and find out how to do this in power query

Hi, @maurcoll 

add new column  using below dax
just adjust your table and column name

Column = 
var a = 'Table (5)'[Order Number]
var b = var a = 'Table (5)'[Order Number]
var b = 'Table (5)'[Date]
var c = MAXX(FILTER('Table (5)','Table (5)'[Order Number]=a && 'Table (5)'[Date]=b),'Table (5)'[Completed by])
return
IF('Table (5)'[Completed by]=BLANK(),c,'Table (5)'[Completed by])
