I created a UD datasource in BW and the "Proposal" tab showed me the correct column names for the table I had selected. A couple of column names were then changed for this table in the source system but they are not showing up in the "Proposal" tab (the old column names are still there). I refreshed and reactivated the source system in BW but it didn't work. Any ideas on how to get the new column names to show up in the "Proposal" tab? Thanks for any help on this.
