Well an aggregator transformation is an active connected
transformation which is used to convert detailed values in
to summary values by using aggregator functions like sum,
avg, max, min etc...if a mapping contains aggregator
transformation the informatica server executes the
expression each for every group of record. The aggregator
transformation is based on four parameters
1)groupby ports
2)group expression
3)stored inputs
4)incremental aggregation
As every one knows an aggregator transformation is active
because it executes less out put than no of inputs(detailed
values in to summarized values)...
By the definition an active transformation is the
transformation in which the no of outputs will be less than
inputs...
by the definition an passive transformation is the
transformation in which the no of outputs equals to the no
of inputs...
corect me if i was wrong....

1)Agregator T/R is used to perform summary calcluation
2) It is Active bcoz the output of this T/R is not equal to
input

Answer / suneelkumar.dasari

C in active T/R the total no.of input records wil be changed(i.e the total input records wont come),but in passive t/r the total no of input records are not changed,and we can add some extra columns.But in Active also we can add columns.

I am hvaing SOURCE as 1000,null,null,null null,2000,null,null null,null,3000,null null,null,null,4000 Now i want the OUTPUT as 1000,2000,3000,4000 For more clarification i want to elimate nulls and want in a single line. Please help me out
