Check if a value appears earlier in a column

[LilMurph]

Hi All

I have a table where one column specifies the week as 1, 2, 3 etc. Another column specifies a job by specific code i.e. ABC-123, ABC-578, CCA-246 etc. 

I want to create a new column which states that a job is new if the code does not occur in the first week. Does anyone have any advice on how to do this as I am drawing a blank.

Thanks

Hi @LilMurph ，

If this doesn't work for you, would you mind providing some data that does not contain private information?

It makes it easier to give you a solution.

1. Sample (dummy dataset) data as text, use the table tool in the editing bar
2. Expected output from sample data
3. Explanation in words of how to get from 1. to 2.

@LilMurph , first week or last week

A new column =

var _cnt = countx(filter(Table, [Job] =earlier([Job]) && [Week] =1 ), [Job])

return

if(isblank(_cnt), "New", "Old")

based on last week

A new column =

var _cnt = countx(filter(Table, [Job] =earlier([Job]) && [Week] =earlier([Week])  -1 ), [Job])

return

if(isblank(_cnt), "New", "Old")
