Column Formulae

Question

I have “Budget” figures of the entire year in a column. I have the ‘Actual ‘ figures in another column for which I have data only for three months.
I need to develop a forecast column which should be the Cumulate Values of Actuals of three months and Budget of the rest of the months.
Month     Actual     Budget      Forecast
1     5     10     5
2     5     10     10
3     5     10     15
4          10     25
5          10     35
6          10     45
7          10     55
8          10     65
9          10     75
10          10     85
11          10     95
12          10     105
I tried using column formula CASE (WHEN) but have only been able to get data only upto the months of actual to a new column.
CASE (D_TIME.FN_MONTH_ID) WHEN D_TIME.FN_MONTH_ID THEN F_BLOCKWISE_CROP.TOTAL_TONNAGE ELSE F_BLOCKWISE_CROP_BGT.TOTAL_TONNAGE END
Can I use “Greater Than”/ “Less than values” in column formulae? I tried but have not worked so far.

Hi,
Yes, you can apply arbitrary functions in your formula using EVALUATE.
Let us suppose You use Oracle Database as a data source.
You want to compare two columns which is the greatest or least;
Please consider the following Oracle BI Server SQL statement:
SELECT EMPLOYEES.FIRST_NAME saw_0, EMPLOYEES.LAST_NAME saw_1, EMPLOYEES.HIRE_DATE saw_2, MONTH(EMPLOYEES.HIRE_DATE) saw_3, EVALUATE('LEAST(%1,%2)',EMPLOYEES.FIRST_NAME,EMPLOYEES.LAST_NAME) saw_4, EMPLOYEES.SALARY saw_5 FROM HR ORDER BY saw_5 DESC
Of course you can use GREATEST and your PL/SQL function as well
(for example) EVALUATE('TAX(%1)',EMPLOYEES.SALARY)
