Creating and Editing a Calendar
Schema 
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.

holiday and factory calendars using transaction SCAL (see 
Calendar); you can
use the selection help to determine the existing public holiday and factory
calendars.
6. In the Operation group box, you can determine how the days defined above should be handled:
Setting |
Description |
Discard Days Above |
The days defined above are not included in the aggregation or reporting |
Keep Days Above |
The days defined above are included in the aggregation and reporting |
Use Day Schema |
For the days defined above, only the hours that are selected in the corresponding day schema are included in the aggregation and reporting |
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.
If you have specified different operations in different day assignments for single days, the day assignment that is further down the list of assignments is always the one that is active.
9.
If you want to
delete a day assignment, choose the Deletepushbutton (
) in the Day
Assignments group box.
10.
If you want to
check how the calendar schema handles the data for which days, choose the
pushbutton Check Calendar Schema (
). You can see whether the data for the days
of the current month is used for the aggregation, not used for the
aggregation, or whether only certain hours are used, based on a day schema. To
check the consequences of the calendar schema for a different time period,
enter the period in the Time Interval group
box.
11. Save your settings.
