Hi Kajar,
Yes for both issues.
You have to keep in mind that the function requires 3 parameters
1) return field, which can be any valid expression, with when, other
functions etc. But remember only one field (or expression) per function call
2) a table name, but can be a view for example
3) a filter expression, which can combine as many boolean expressions as
necessary. Here the most important point, this expression should return only
1 line, or none. If you return more than one you will have an error of
exception. The trick here is to combine the expression with the values you
have from your main table. Knowing how to do this, the sky is the limit !!!
