Information Broadcasting

Hi Friends

good day to you.

I have the following scenario.

1. Query developed for Market segmentation

2. I have records which are not assigned to any of the segments under Unassigned segmented records

3.Now i need to send a mail to particular group of people only the Unassigned records information not the Assigned once so that they can correct the data.

How i need to configure these type of situations in Broadcasting.

Thanks for your help.

regards

sunder
