Spreading the value across the column

[hcbn]

Hello

I have a question.

If the value is equal to 12 then I need to divide the qty column to the EOQ column. The result will be spreading in the requested output until the total is 12. If the value less than 12 then I will keep it as it is.

Input
qty	EOQ
12	4
0	4
0	4
0	4
0	4
0	4
0	4
0	4
4	4
0	4
0	4
0	4
2	4
0	4
0	4
12	4
0	4
0	4
0	4
0	4
0	4
0	4
0	4

Output
qty	EOQ	Requested Output
12	4	3
0	4	3
0	4	3
0	4	3
0	4	0
0	4	0
0	4	0
0	4	0
4	4	4
0	4	0
0	4	0
0	4	0
2	4	2
0	4	0
0	4	0
12	4	3
0	4	3
0	4	3
0	4	3
0	4	0
0	4	0
0	4	0
0	4	0

;

data want(drop=c temp);
   set have;
   Requested_Output=qty;
   if qty>0 then Requested_Output=qty;

   if qty=12 then do;
      Requested_Output=qty/EOQ;
      temp=Requested_Output;
      c=temp;
   end;

   if qty=0 and c<12 then do;
      c=c+temp;
      Requested_Output=temp;
   end;

   retain c temp;
run;
