Calculate the total number of Business days present in a Month as per Organization/Company calendar

Introduction

Hello Everyone,

The purpose of creating this table function is to calculate the  key figures which are very important for Target Vs Sales Analytical reporting. This Key figures can be referenced in Predictive Sales reporting.

The functionality of the following  four key figures :-

  1. Total No of Business/Working days (“Total_WDS”) in a January 2020  is “22”. Please refer the below calendar snapshot. Count the yellow highlighted box which is an Working day as per calendar. And red border highlighted box i.e 23rd Jan,2020 is an Holiday.

Output :

 

2.  Is “Today Working ??(TODAY_WD”)-  The Input Date is a business day or an Holiday. This measure output is boolean (“Y/N”). For e.g input date 23rd Jan, 2020  will return “N” as  this  is an public Holiday.

output:

3. “Current working days”(“CRNT_WD”) – Returns the Current no of working days. For e.g Input date  20th Jan, 2020, no of working day is “14” . Count the yellow color highlighted box.                                                                                                                                                                                                                           

Output:

4. “Working Day in %(Percentage)” (WDS_PRCNT)-   The formula is

(“CRNT_WD”/”TOT_WDS”)*100

Use Case of the following key Figures:

I have addressed the requirement of Sales business reporting. This above calculated key figures can be referenced in a “Predictive KPI” calculation. For e.g if a  Sales Person sold an x no. of material  till 7th Business day of the month then how many more no of material can he/she sell in the remaining no of working days.

This requirement was very common in “Target Vs Actual Sales” reporting requirement. So I Shared this code with you all.

 

This table function can be consumed directly in the SQL code, Stored Procedure or any Calculation Views. In my case i consumed in a calculation view.

 

Input Parameter :  One Input Parameter of Varchar data type of Size 11 (Date format  ‘2020-01-20’)

Conclusion –

This Table Function will return the no of working days and the Current Working day as per employee Calendar in a specific month. This calculated key figures can be references  can be consumed for Predictive calculation and any Sales fact table.
