create a mapping variable name $$max_bound of integer data type and aggregation type max
now in expression variable
seq v seq+1
o_seq o seq
v_temp v v_temp+1
curr_val v IIF(v_temp=1,setmaxvariable($$max_bound,$$max_bound+2),0)
o_map_val o setvariable($$max_bound,NULL)
now come to filter transformation
and write condition as
(seq<=$$max_bound)AND(seq>$$max_bound-2)
Thanks

Answer / naveen
You are right , this can be achieved only with the help of
the mapping variable. and also a filter transformation
1) create a mapping variable and assign a default value 0
2)during the first run , i hope ur source must have an seq
num in it, if not use the seq gen and have unique sorted
record.
3)in a n expression , just have v_max_filter =
@@map_variable + 2 and v_min_filter = @@map_variable - 2
4) in the filter transformation , put the filter on the
seq_column <= v_filter and seq_column >= v_min_filter
5) enjoy a coffe, this will run

What is meant by incremental load?
how would u estimate the size of Lookup transform data and index cache?
what are the data modeling tools you have used?(polaris)
Do we need an etl tool?
what is HISTOGRAM? how to generate statistics?
what is session partitioning?
what are the parts of Informatica server ?
how do u estimate the number of partitions that a mapping really requires? Is it dependent on the machine configuration?
