Help in Look up Logic

Question

I need a help in the look up logic to be implement it in ODI.
I am having a source table and a look up table. Look up table contains few conversion rules in it like so & so account has to go to so & so account etc.
So when I move my source to target I've to look at the Look-up table to check if the account exists. if it does change it to the change it to the corresponding account given in the look-up table. Also the Look up table is going to have ranges. 2 fields. 1 would tell the starting(lets say 100) and second fileld would give the end(lets put 200).
So If the account falls between 100 and 200 change it to corresponding account in the table.
Please help me out in this logic. Also please let me know what are the KM's I would need for this. My source,LKP and target are all Oracle tables from the same schema if this helps.

Hi,
Trying to help.
If I understood your requirement correctly,
You can achive this using a join (outer) and case statements in your interface level.
In interface level use join (your source and lookup table - all records from source )
Use proper Case statements in the target column mapping ( in your case need to write case statements based upon accounts)
By this statemnt
"If the account falls between 100 and 200 change it to corresponding account in the table",
I hope you need to update the data in your target table itself ; if so add that range conditions also in your case statement.
Hope this will help to solve the issue (if not please send a sample records of the source , lookup and target tables)
