Previous row with IF formula in Power BI

[prithivi97]

Hi there, I am trying to convert below given excel formula into power bi formula:

: =IF((I4<>I5)*(E4="No"),"Current",IF((I4<>I5)*(E4="Yes"),"FDR","Not relevant"))

I have created the index row starting with 0, 1.. to find the previous value - however, the return value isn't correct in power bi. below is my formula: 

: Column FDR = IF([Position ID] <> [Last Position ID]*([4. Today]="No"), "Current", IF([Position ID] <> [Last Position ID]*([4. Today]="YES"),"FDR", "Not Relevant"))

The return values are only "Current" and "FDR". Although, FDR only should come in YES but it shows for No and Current shows for Yes & No. I am not sure what i am missing in this formula...

Really appreciate your input in this problem..

Hi, thank you for responding..

Position ID is the data set and first three columns are excel formula columns. 

1. Concat - just random date generated in system and i changed the format to (dd/mm/yyyy). 

2. > Today? - =IF(D3*1>TODAY(),"Yes","No")

3. FDR =IF((G3<>G4)*(E3="No"),"Current",IF((G3<>G4)*(E3="Yes"),"FDR","Not relevant"))

             So technically, if position ID G3<>G4 and >Today is No = the return value should be Current.

             If the psoition id G3<>G4 and > Today is Yes = the return value should be FDR (if true) Not                       relevant (if false)

	Column D	E	F	G
	Concat	> Today?	FDR?	Position ID
3	3/4/2019	No	Not relevant	50000457
4	30/4/2019	No	Not relevant	50000457
5	20/6/2019	No	Not relevant	50000457
6	1/9/2019	No	Not relevant	50000457
7	24/10/2019	No	Not relevant	50000457
8	7/11/2019	No	Not relevant	50000457
9	26/3/2021	No	Not relevant	50000457
10	1/4/2021	No	Not relevant	50000457
11	13/9/2021	No	Not relevant	50000457
12	1/10/2021	No	Current	50000457

In power bi - i have created index column and index_1 to get the last position ID (below cell position id). but the return value in power bi is not as expected. Below was the if function measure i used in power bi.

Column FDR = IF([Position ID] <> [Last Position ID]*([4. Today]="No"), "Current", IF([Position ID] <> [Last Position ID]*([4. Today]="YES"),"FDR", "Not Relevant"))
