Hi Gopi,
This is the kind of error that can be a bit frustrating.
One approach is to narrow it down by adding the 3 new fields one at a time.
This will at least identify the one new field when the issue starts to occur.
Which query subject does that field come from? It is probably not from one of the query subjects already in this query.
If you have access to FM, it may be easier to track down how the queries are related to one another.
Please post how things are going.
