Hi Listers,

I have a question related to data manipulation. My data sample is like that:

Parent       Subsidiary
A            B
             C
             D
             F
X            J
             L
Z            T

What I want is to fill the gaps of the ParName. This is to replace the missing values of C, D, F with A, and the missing value of L with X. Each Parent has a different number of Subs.
Any ideas?
Thanks in advance.

Regards,

Socrates
