I have a situation... Datatype of one of the column in the Database is going to change. That column is being used in my OBIEE reports. Wanted to know whether the report holding this column will be impacted because of this change???
I not a expert but report use name from repository(presentation layer). You have to make changes only in BM and mapping( you can change mapping in logical table source) and physical layers. You have to consider where this name is use in this two layer. After this test it:)
