Retrieve a record and modify it using Java API

Hi,

I'm trying the following scenario using Java API in MDM.

I query a MDM MAIN table called "Vendors". I get a result set.

Now, i try to pick a particular record to modify one of the fields called "Vendor Number". My objective is to Update a field called Vendor Number in that table with a text.

Can you provide the code snippet to Capture a record and Update a particular field alone?

Thanks in advance,

regards,

Ak.
