Utility to Upload BOM in Custom Format.

Hi

I am building a utility to import BOM in customer format.

Requirement is:--

1. User will upload BOM in CSV format.

2. User can preview CSV in HTML and validate before uploading to windchill.

3. CSV wont be uploaded or lets say BOM wont be uploaded if there is any error in Line item.

4. Result of Upload Process should appear against CSV rows in HTML.

Please suggest.
