I have the following data

Case_number Company  party_role
1 A Plaintiff
1 B  
1 C Defendant
1 D  
2 E Plaintiff
2 F  
2 G Defendant
2 H  

 

 

I want the output to look like this. 

 

Case_number Company  party_role
1 A Plaintiff
1 B Plaintiff
1 C Defendant
1 D Defendant
2 E Plaintiff
2 F Plaintiff
2 G Defendant
2 H Defendant

 

I tried following code but not working 

 

data want;
set have;
retain repeat1;
if first.case_number then do;
if party_role ne '' then repeat1 = party_role; else do;
if party_role eq '' then party_role = repeat1; end; drop repeat1;
end;
run;

then do;
  if party_role ne ''
  then repeat1 = party_role;
  else do;
    if party_role eq '' then party_role = repeat1;
  end; 
  drop repeat1;
end;
run;

Do you see the logic mistake?

The log will also alert you to the fact that you tried to use a FIRST. variable without a corresponding BY.

 

BTW, DROP is a declarative statement. Putting it into a conditional branch is at best misleading.

You probably want this:

data want;
set have;
by case_number;
retain repeat1;
if first.case_number then repeat1 = "";
if party_role ne ""
then repeat1 = party_role;
else party_role = repeat1;
drop repeat1;
run;
