Hi I setup a number of named queries and then decided I needed to use 2 of these on a chart. So I ticked both the named queries and created a new named query. I applied it to the chart and it was all working fine. I then went to data manager and changed one of the fields (not on that was being used in the chart or that was used in the queries (completely unrealted)). I went back to chart to find that the query no longer works and I have to rebuild it. What am I doing wrong? Thanks Neil
