The time-independent definitions of seasons and season years and the time-dependent definition of seasonal patterns form the basis for seasonal planning. You need this master data to be able to assign the corresponding season years to the characteristic values combinations of a planning area.
You can also define the assignment rules for the automatic assignment of seasonal patterns to characteristic values combinations.
You can transport the definitions of the seasons, season years, and seasonal patterns together with the corresponding planning area to another system.
You require the following master data for seasonal planning. Since the various kinds of master data build on each other, create them in the sequence described here.
You use seasons to specify the names of the individual periods.
You specify the seasons and the sequence of the seasons in a season year. Each season year can have up to 99 seasons.
You specify the start and end dates of the individual seasons in a seasonal pattern, which is based on a season year. You can define more than one seasonal pattern for a season year, in which the seasons can be of different lengths.
Each seasonal pattern uses a specific periodicity (such as months). If you use a seasonal pattern in a planning area, the periodicity of the seasonal pattern must be contained in the storage buckets profile of the planning area.
When you have specified the length of the seasons, you can define the year-dependent structure of the season year (optional). Here you can change the start and end dates of individual seasons dependent on the year. This is necessary, for example, if you want the seasonal pattern to deviate from the year-independent definition for specific years.
You use assignment rules to determine which characteristic values combinations of a planning area you want the system to assign specific seasonal patterns to. Before you define the rule, specify the required assignment levels. In the assignment levels, you restrict the available characteristics to the characteristics for which you want to specify the rules. For this you enter a hierarchy. This means that each additional assignment level must contain the characteristics of the previous assignment levels.
During assignment later on, the system tries to find as exact a match as possible between the characteristic values combinations of the planning area and those in the assignment rule. In doing so, the system always considers the more specific rule before the less specific rule.
So that the system considers the assignment rules during assignment, you must first activate the rules. You make the assignment by starting the rules-based assignment. For more information, see Assigning Seasonal Patterns to Characteristics Combinations.
