Hi,

Thank you for posting a picture of some sample data. I have a few questions for you:

• Is the data coming from an Excel spreadsheet, csv file, etc?
• In your data, will the email for row 1 always be missing?
• What is the relationship between the ID and the emails? I noticed the emails for A and B both correspond to ID 1. 
• Is the purpose to create a new table or a report?
• What code have you tried thus far?

@vskon Please help everyone out by changing the Subject on your original post to something that describes the problem. "SAS Code" is not a meaningful description. Something like "Filling in Blank Lines" would be a much better subject, it is a meaningful description of your problem, and it allows the SAS Community to operate more efficiently, people with a similar problem can see this meaningful subject line and read the responses.
