DAX to replace value with another in same column depending on 2nd column
Hey all,
I have a curious problem due to the way data I am using is stored.
I have the table below .And I need to replace the ID (column a) of all the rows where Level is = 5, with the ID of the same Idea (column b) where the level is = 4. So the unique ID of Ideas at Level 4 is linked to some data I also need for Level 5.
I've tried creating a new column to use for this purpose with the DAX below; but it gives me "A table of multiple values was supplied where a single value was expected". I've tried wrapping it all in FIRSTNONBLANK with same result.
IL5 to IL4 =
FIRSTNONBLANK(ImplementationLevel[ID]; IF(
VALUE(ImplementationLevel[Level]) = 1;
LOOKUPVALUE(ImplementationLevel[ID];ImplementationLevel[Idea];ImplementationLevel[Idea];ImplementationLevel[Level];"1");
IF(VALUE(ImplementationLevel[Level]) = 2;
LOOKUPVALUE(ImplementationLevel[ID];ImplementationLevel[Idea];ImplementationLevel[Idea];ImplementationLevel[Level];"2");
IF(VALUE(ImplementationLevel[Level]) = 3;
LOOKUPVALUE(ImplementationLevel[ID];ImplementationLevel[Idea];ImplementationLevel[Idea];ImplementationLevel[Level];"3");
IF(VALUE(ImplementationLevel[Level]) = 4;
LOOKUPVALUE(ImplementationLevel[ID];ImplementationLevel[Idea];ImplementationLevel[Idea];ImplementationLevel[Level];"4");
IF(VALUE(ImplementationLevel[Level]) = 5;
LOOKUPVALUE(ImplementationLevel[ID];ImplementationLevel[Idea];ImplementationLevel[Idea];ImplementationLevel[Level];"4"))
)))))
Anonymous Could you please check and confirm... whether the data contains same idea (duplicates) at same level (in this case it is 4). Even though it has a different ID.

Anonymous Please try this as a New Column
NewID = VAR _CurrentIdea = Test178CondReplace[Idea] VAR _Level4ID = LOOKUPVALUE(Test178CondReplace[ID],Test178CondReplace[Idea],_CurrentIdea,Test178CondReplace[Level],4) RETURN IF(Test178CondReplace[Level]=5,_Level4ID,Test178CondReplace[ID])
Hey PattemManohar
Thanks for the suggestion. I'm getting the same error.
NewID = VAR _CurrentIdea = ImplementationLevel[Idea] VAR _Level4ID = LOOKUPVALUE(ImplementationLevel[ID];ImplementationLevel[Idea];_CurrentIdea;ImplementationLevel[Level];"4") RETURN IF(ImplementationLevel[Level]="5";_Level4ID;ImplementationLevel[ID])
I've put the Levels in "" as they are formatted as Text (elsewhere I don't want them to be treated as numbers).
Why does it return multiple values? ID column is unique values.
