Is it possible to exclude Weekends for Days open calculation in BI reporting? 

Content (required):

Hi,

We have a requirement to identify the Requisitions which are posted internally for 7 Business days (Excluding weekends and Holidays). Is there a way to calculate Business days alone using SQL query? I know the holidays can be identified using calendar tables, but we are stuck with finding ways to exclude weekends in our query.

Hi

Below query snippet will help to identify the days excluding weekends.

D_DAY is the time dimension at day level.

You need to pass requisition creation date as 1-Jan-2022 and requisition end date as 15-Jan-22 in the query as commented below to calculate requisition posted days. You need to replace them with actual db column during the calculation logic.

This query assume the weekend is on SAT and SUN.

SELECT COUNT(DAY_DT) -- REQUISITION_POSTED_DAYS

FROM D_DAY

WHERE DAY_DT BETWEEN '01-JAN-2022' --REQUISITION_CREATE_DT

AND '15-JAN-2022' --REQUISITION_END_DT

AND TO_CHAR(DAY_DT,'DY', 'NLS_DATE_LANGUAGE = AMERICAN') NOT IN ('SAT','SUN')

Hi Venkata,

D_DAY is invalid table and im getting error when i run this query. Is this query working for you?

Thanks,

Abhishek.

Hi Abhishek

You need to replace the D_DAY with your actual time dimension table. This table is given for reference purpose.

If you are using FAW, then I think the table is W_DAY_D. Pls give a try

Hi @Abhishek Jois,

This can be handled if you have a proper calendar dimension associated with your data model. Most calendar dimensions will have a column CAL_DAY_OF_WK, which correspond to the numerical day of the week. You could either extend your calendar dimension to include a weekday flag by generating a logical column where CAL_DAY_OF_WK NOT IN (7,1) or use a filter in your reporting layer with the same logic.
