Hi All,

 

I have this dataset:

Exposure  Name

101           Sandra

101           

 

101           Tiffany

101           Abel

101

101           

 

I Want :

Expsoure  Name

101           Sandra

101           Sandra

101           Tiffany

101           Abel

101           Abel

101           Abel

 

How can I carry forward character value to subsequent missing rows until it reaches a non-missing cell.

I tried using lag but it doesn't work if more than 1 row has missing value.

 

Thanks!
