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

how do u identify the changed records in operational data?
Suppose I am loaded with questions as I am an experienced etl coder, but not an analytical report builder. I am using analysis services to build a cube but am trying to choose the reporting architecture. Can someone please confirm whether or not reporting services (using the business intelligence report) will allow for slicing and dicing, or is it only a static report builder. Also, if I am using the cube browser in analysis services, where can I put the option of non empty so that I dont see records that are blank.?
