Hi Venkatdas,
From the SQL perspective:
Filter criteria you specified in the "Filter" directly goes in WHERE clause.
e.g. If you have sales order data, if you only want to display sales org 1000 data.
SELECT * FROM ORDERS
WHERE sales_org = '1000'
In case of "FILTERS" you can only apply criteria on "Characteristic", you can't apply criteria on keyfigure value.
Where as in case of "_Restricted Key Figure_", instead of limiting the entire data set you will be limiting a keyfigure based on a characteristic value.
e.g. If the requirement is to show the data by division by current year vs. prior year comparison in columns.
Current Year Prior year
Division
10 $104,000.00 $8,320.00
20 $138,666.67 $124,800.00
30 $242,666.67 $169,866.67
SELECT  DIVISION, SUM( DECODE(YEAR, 2010, SALES$s, 0) ) , SUM( DECODE(YEAR,2009, SALES$s, 0) )
FROM ORDERS
GROUP BY DIVISION.
As you can see incase of "Restricted Keyfigure" entire data set is not restricted; instead a value of the output is restricted based on a characteristic value.
Condition, no data is limited at database level. From the SQL perspective there would not be any data restrictions. Once the data comes to OLAP layer, you would apply a condition to only show data meets a criteria.
e.g. Display only top 10 materials.
SELECT MATERIAL SUM( SALES$s)
FROM ORDERS
WHERE YEAR = 2010
GROUP BY MATERIAL.
The above statement would output all the material and the corresponding sales in year 2010. Once these rows comes to OLAP layer, CONDITION will kick-in and sort the data by SALES$s and only display to 10 materials.
Cheers,
