Please guide me to write a Knowledge Module(KM) in ODI.

Question

I am using ODI for my Batch Processes.
I am using LKM Oracle SQLLDR for bulk upload. LKM upload flat files data into staging area (C$ Table). After uploading, IKM SQL Control Append transfer data from C$ table to My Oracle Table. IKM transfer data from I$ table to target table after validation using Oracle CKM. It is working fine.
But my business need are different.
My C$ table contains all fields as String data types. But my target table contains some of NUMBER data types fields. In this case IKM stop data transfer due to INVALID Number exception. I want to transfer that record to my custom error log tables using PL SQL statement.
Note: SQL LOADER can generate .bad file if I set all fields of file data store as target data store. But We didn't want to make bad files for these kind of problems.
If any solution is available in ODI then please suggest me. As per my conclusion, I need a IKM who support this kind of functionalities.
Please help me out.

Answer 1

I see two ways:
1 Use ODI built-in checks for Complex Conditions (has alphabetic values)
In this case you at first load data into staging area (as strings), then apply static checks with above said complex conditions to filter out "error" records. And then load data from these tables further.
2 Modify LKM, by adding such kind of logic:
All table fields marked as UserDefined 1 are filtered to have alphabetic characters at loading and are separated into 2 tables, "good" and "bad" one
To achieve this you should duplicate loading steps and apply regexp filtering to them and add another target table step creation with _bad suffix to load errors to.
