Totaling a column and dividing it by the original value

Hello - I am using enterprise guide 6.1.  And what I am looking to do is sum a column and divide the total by one of the values that I added to get the percent of the total.  We just recently upgraded our SAS from 4.3 to 6.1 and this same program in 4.3 had this as the computed column:

Paid/Sum(paid)  - Which would give me the percent of the paid amount for the facility to the total paid amount.

when I do that same formula in SAS enterprise guide 6.1 it only gives me a value of 1 because it is simply dividing the value with itself. 

Is there a formula or function that I could use to help me get a percent for the paid amount in SAS 6.1?  I am using the computed columns - Advanced expression editor.  Please help!  Thank you.

Re: Totaling a column and dividing it by the original value

I think your group by clause is too restrictive, its unusual to group by calculated items (but sometimes necessary).


Try reducing it to only what you need, FACILITY is my guess...since I'm assuming you're calculating the stats over each facility.

Re: Totaling a column and dividing it by the original value

Can you post the query that doesn't work (view code from EG).

My guess is that a GROUP BY clause is missing.

Re: Totaling a column and dividing it by the original value

PROC SQL;

   CREATE TABLE WORK."Details" AS

   SELECT t1.'Facility Name'n,

          t2.LOS,

          t2.Admits,

          /* Avg LOS */

            (t2.LOS/t2.Admits) LABEL="Avg LOS" AS 'Avg LOS'n,

          t1.Charged,

          t1.Allowed,

          /* % of Discount */

            ((t1.Charged-t1.Allowed)/t1.Charged) LABEL="% of Discount" AS '% of Discount'n,

          t1.Paid,

          /* % of Total Inpt */

            (t1.Paid/SUM(t1.Paid)) LABEL="% of Total Inpt" AS '% of Total Inpt'n,

          /* Allowed/Day */

            (t1.Allowed/t2.LOS) LABEL="Allowed/Day" AS 'Allowed/Day'n

I set the formula to bold that is not working.

Need the full query, especially the group by clause.

QUIT;

It worked.  I unchecked 'Automatically select groups' and it worked.  Thank you.
