Answer / rajesh.a
We need to use sorter,Expression and aggregator transformations to do this
1.Sort by ID
2.Take 2 variable ports one for id and one for name and store the values of id and keep on comparing with current id i.e variable is having previous id.
so,if previous id=current id then (variable name)||name otherwise only name.assign the variable name to output port
3.Use aggregator and use last or max(len(name)) to get the result

What will happen if we have a filter transformation used in a mapping and in the filter condition we specify 1. Yes nothing else, only the number 1. In other words, assuming we have 10 rows coming to this filter transformation as an input, how many rows will be output by this transformation when we have only 1 in the filter condition?
what is the flow?
