Creating and Editing a Calendar Schema CCMS

Use

A calendar schema specifies which days should be considered during the aggregation to weekly, monthly, quarterly, or yearly values. You can create your own schemata or edit existing schemata.

Create a calendar schema to ensure that only the periods that are relevant for you are stored in the Central Performance History (CPH). You can, for example, remove weekends or public holidays from the calculation of aggregates.

Procedure

1.You can call the editing of calendar schemata from several functions:

¡ In the overview screen of the CPH (transaction RZ23N), choose, in the Data Collection and Reorganization group box, the Calendar Schemata pushbutton.

¡ On the screens on which there is an input field for entering a calendar schema, you can use the selection help to obtain a list of all existing calendar schemata. On this screen, choose Display Details ().

2.In both cases, the Edit Calendar Schema screen appears. Here you can view the definition of the selected calendar schema:

3.To edit a different calendar schema, enter the desired schema in the Name of the Calendar Schema input field. To create a new calendar schema, choose the Create Schema pushbutton ().

4.Enter the desired name and a description for the schema.

5.You can formulate a condition to select certain days in the Day Definition group box. In this way, you can define days using the date and the weekday, and further restrict this set using a public holidays calendar, factory calendar, or a single public holiday.

Setting	Condition
Day, month, year: any(*); Week day: Saturday; Additional restrictions: None	All days that fall on a Saturday

7.Together, a day definition and an operation form a day assignment, which specifies which days are included in the aggregation, and how they are included. Choose the Add () pushbutton to include the day assignment created above in the definition of the calendar schema.

8.Repeat steps 5 to 7, until you have created all required day assignments.

To check the consequences of the calendar schema for a different time period, enter the period in the Time Interval group box.
