Processing flat file within ODI

Question

Friends,
I need to read a flat file consisting of 'detail or main record' and 'trailier Record
1) Detail Record consist of each transaction details including amount etc.
2) Trailer Record consist of total value on detail records ( number of records and total amount)
How can I verify the total amount in trailer against sum of all detail records?
Thanks
KS

Answer 1

hehehehe
Was a "bad way" to say "execute the calculations".
An way to do it is:
1) create a ODI variable
2) at refresh tab put something like
select t.col_trailier_sum_amount - sum(d.col_amount)
from loaded_tabledetail d, loaded_table_trailier t
where d.record_type = 'detail' and t.record_type = 'trailer"
group by t.col_trailier_sum_amount
* I'm using 2 tables at this example but is the same with just one...
3) create a package and drag and drop:
a) the interface that load the temp table
b) the variable in Refresh mode
c) the variable in evaluate mode ( set the evaluate operator to "=" and value to "0")
d) choose the OK (true) and KO (false) path that you need to each case
Does it make sense to you?
