...populate top five decimal values...

Could you explain what you mean by that? Is it the rows with the 5 largest values in one column, or 5 decimal columns and getting the highest among them or some other action?

It is to populate five largest decimal values.

rank the columns and then based on column ranking filter only the first five records.

p.s i am sure your next question would be how to rank. for that search the forum :D

Sort the data by descending value, then limit the output to the first 5 rows.

How to limit the output to the first 5 rows

[ArndW]

single-thread a transform stage (sequential as opposed to parallel, or a 1-node configuration) and then put a constraint "@INROWNUM < 6" in.
