Function documentationBusiness Week Definition

 

Forecasting & Replenishment (F&R) stores data for weekly processes, such as weekly consumption and forecast data for a particular product. F&R uses weekly information for display (for example, in the Replenishment Workbench Time Series Screen and DIF Calendar) and reporting purposes. The definition of what is considered a “business week” may be different in different countries or organizations.

In Europe, Monday is considered the first day of the week, while the United States uses Sunday as the first day, and Saudi Arabia uses Saturday. Therefore it is important to define the starting day of the week and how the system is to calculate the first week of the year.

Integration

In Customizing (IMG path: Forecasting and Replenishment > Master Data > F&R Customizing on Client Level), you must make the following entries:

  • First Week Day

    You enter the weekday you want the system to use as the start of a business week.

    Caution Caution

    Once you enter a date here and save it, you will NOT be able to change it again as this would invalidate any time series data generated with the previous setting. When you choose Save, the system displays a message asking you if you are sure you want to save this day. Check your entry carefully before proceeding.

    End of the caution.

  • First Week of the Business Year

    You make entries in these fields to specify how the system calculates the first week:

    • Day of Reference Date

      Enter the number of the day of the month you want to use as a reference point.

    • Month Reference Date

      Enter the number month you want to use as a reference point.

    • Determination Rule of Business Week

      Select the rule you want the system to use for the calculation. You can either select one of the standard rules, or use BAdI /FRE/DB_MD_BADI_006 to create your own rule.

For Europe, the week begins on Monday, and the first week of the year (calendar week 01) must contain three days after the reference date (January 1). In this case, January 1 is a Saturday, and the following three days fall into the next week. Therefore, the system determines that the first business week of the year starts on Monday, January 3.

In the United States, the week begins on Sunday, and the first week of the year is the week that contains the reference date. If you entered January 1 as the reference date, then according to the calendar, this day is actually the last day of the last week of December 2004. Therefore the system determines that the first business week of the year 2005 starts on Sunday, December 26, 2004.
