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.

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..

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

few options:
1. did you place any other trans before Agg t/r
2. check how many rows are comming form source.
3. run the debuger for more info
