Match Formula for the same unique value

The previous title was not fulfilling my requirement

Hi
I need a formula in D column of the attached file, I have updated D column as per the expected result with the below requirement.
1) If “C” column is “Successful” then in “D” column, for all same unique value it should “Successful”
2) If “C” column is “Reject” then in “D” column, for all same unique value it should “Successful”

Better - thanks.

Try this instead:

=IFERROR(IFERROR(IF(LOOKUP(2,1/(($CK$2:$CK$15=CK2)*($CM$2:$CM$15="Successful")),$CK$2:$CK$15)>0,"Successful"),IF(LOOKUP(2,1/(($CK$2:$CK$15=CK2)*($CM$2:$CM$15="Reject")),$CK$2:$CK$15)>0,"Reject")),"")

Perhaps better would be this:

=IFERROR(IF(LOOKUP(2,1/(($CK$2:$CK$15=CK2)*($CM$2:$CM$15<>"")),$CK$2:$CK$15)>0,LOOKUP(2,1/(($CK$2:$CK$15=CK2)*($CM$2:$CM$15<>"")),$CM$2:$CM$15)),"")
