Alternating Attributes in new columns
Hello,
I have a mastercalendar as an example. I didn't show all dates just the calendarweeks for simplicity here:
| Calendarweek | Category A | Category B | Category C | |||
| 1 | A | B | C | |||
| 2 | B | C | A | |||
| 3 | C | A | B | |||
| 4 | A | B | C |
I want category alternating for the weeks to come. So in week one of Category A it starts with A and then B and then C and again A.
Its a regular alternating pattern. How to write this as a calculated column and also starts the other categories with B for week 1 repsectively C for Category C?
Thank you very much in advanced.
Best.
Category A = {"A","B","C"}{Number.Mod([Calendarweek]-1,3)} Category B = {"B","C","A"}{Number.Mod([Calendarweek]-1,3)} Category C = {"C","A","B"}{Number.Mod([Calendarweek]-1,3)}See the working here - Open a blank query - Home - Advanced Editor - Remove everything from there and paste the below code to test (later on when you use the query on your dataset, you will have to change the source appropriately. If you have columns other than these, then delete Changed type step and do a Changed type for complete table from UI again)
let Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlSK1YlWMgKTxmDSBEyagkkzMGkOJi3ApCWYNDSAUBDdhhDthhD9hkADYgE=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Calendarweek = _t]), #"Changed Type" = Table.TransformColumnTypes(Source,{{"Calendarweek", Int64.Type}}), #"Added Custom" = Table.AddColumn(#"Changed Type", "Category A", each {"A","B","C"}{Number.Mod([Calendarweek]-1,3)}), #"Added Custom1" = Table.AddColumn(#"Added Custom", "Category B", each {"B","C","A"}{Number.Mod([Calendarweek]-1,3)}), #"Added Custom2" = Table.AddColumn(#"Added Custom1", "Category C", each {"C","A","B"}{Number.Mod([Calendarweek]-1,3)}) in #"Added Custom2"

Since you are saying calculated column, hence I am assuming you need DAX solution
For Category A =SWITCH(MOD(Table1[Calendarweek]-1,3),0,"A",1,"B",2,"C") For Category B =SWITCH(MOD(Table1[Calendarweek]-1,3),0,"B",1,"C",2,"A") For Category C =SWITCH(MOD(Table1[Calendarweek]-1,3),0,"C",1,"A",2,"B")Vijay_A_Verma thanks for your quick reply. Sorry that I wasn't clear. I wanted to see also an alternative in PowerQuery in a added column. I want to compare a DAX and a PowerQuery M approach.
Hope you can also show how it would look like in PowerQuery when I add a new column. (Not calculated column here)
Thanks!
