Hello All,

I have this dataset:

And need your help to obtain Cumulative_subtotal and Cumulative_subtotal_id fields:

Create multiple cumulative subtotals of amount that cover/hedge Needi.

Cumulative_subtotal=30>=Need1=20 end of id=1;

Cumulative_subtotal=22>=Need2=15 end of id=2;

Cumulative_subtotal=13>=Need3=10 end of id=3;

Cumulative_subtotal_id=0 means not needed.

Thank you for your help,

Your explanation helps.  Here is one possibility.

data want;

   cumulative_subtotal=0;

   retain cumulative_subtotal_id 1;

   array need {3} ;

   if cumulative_subtotal_id = 0 then total_need = 9999999999999999;

   else total_need = need{cumulative_subtotal_id};

   do until (cumulative_subtotal >= total_need);

      set have;

      cumulative_subtotal + amount;

      output;

   end;

   cumulative_subtotal_id + 1;

   if cumulative_subtotal_id > 3 then cumulative_subtotal_id=0;

run;

It's untested code, so you may need to tweak it.  But it should have enough working pieces.  Usually when a program is this clunky there is an easier way.  I'm just not seeing it right now.

Good luck.

What in the data tells that an id group is starting or ending?

An id identifies a subtotal: amounts that fill needi must have id=i. The id=i  ends when amount is no longer required for fill needi.

Astounding,

Thank you for your help. Works perfectly in my example Smiley Happy. I just did a very small adjustment for cases when I have Needi=0 (ex. Need2=0, no amount is necessary to fill).
