Please help us by modifying the subject on your original message to "Retain values down columns"

 

data want;
    set have;
    retain npo_orderedinstant1;
    if not missing(npo_orderedinstant) then npo_orderedinstant1=npo_orderedinstant;
run;

 

You can do the same thing for variable npo_order, so I leave that as a homework assignment for you.

Search for methods to implement Last Observation Carried Forward (LOCF).

 

You can normally do this very easily by using the UPDATE statement to treat the data as a series of transactions.  Include an OUTPUT statement to preserve the individual observations instead of just the final result of applying all of the transactions.

data want;
  update have(obs=0) have;
  by identifier;
  output;
run;
