Generic Object Services

Hi Experts,

My doubt is uploading a file from the presentation server, which consists of the fields | Company code | Contract Number | Title of Note | Description |

Depending on the Company code and Contract Number, i want to upload the Title of the Note and its Description into the Transaction RECN.

I heard that there is way to upload the large volumes of Notes...by using Generic Object Services...

Please let me know how to solve this

Thanks in Advance...
