Hello,

I want to transform a simple column in otbi into a measures to create a filter :

I want to create a column to display the pedagogical cost as colum and not a row field, I wan to have one line per offering with column for pedagogical cost and another colum for logical cost :

 so i create a filter column like this :

FILTER (case when ("Learning Record Measures"."Learner Count" )> 1 then 
("Cost Details"."Cost Details Line Amount" )  end )

 USING ("Cost Details"."Cost Details Line Type" = 'Coût logistique'))
