Answer / srinivas.medagum

When the records come from SQ each record from first one
checks for the group by port but till last record it doesnot
found .So by default as the last record considered as only
record it stores in Agg T/R.

Answer / ankit kansal

By Default informtica finds a group on the basis of your group by check boxes and returns you last row of each group when you don't specify any group by clause then it takes whole data set as a single group and returns you the last row of that whole group...

please make me correct if i am wrong..

Answer / naresh_infa96

If you're using Aggregator Trasnformation without using group by on any port then the aggreagtor TXNs consider whole table as one group and gives the last row as output.

Why last row as Output : by default aggregator uses MAX() function
