| In the Calendars and Periods module, you can define and organize calendars for all parts of ERP LN. A calendar in ERP LN establishes the times that resources are available. Example: Production orders can be planned on work center AA from 6 A.M. until 5 P.M. Sales orders can be picked and dispatched from warehouse XY from 7 A.M. until 6 P.M. Calendar structure Calendars in ERP LN can be used in a flexible way. Either base the planning for a whole company on one calendar or define separate calendars for a variety of resources (work centers, sales offices, employees) to plan their times individually. Calendars have a hierarchical structure. A parent calendar provides the default data for the child calendar. Thus, you only need to define the exceptions for the parent calendar. For more information, refer to Calendar hierarchy. You can link calendars to various levels of your organization. The company calendar is the most general calendar. Calendars for enterprise units, departments, work centers, warehouses, and employees are more specific. The company calendar contains working days, holidays, and working times for your entire organization. For delivery planning, link calendars to business partners and addresses. For more information, refer to To use calendars. Availability types A calendar can have multiple availability types with different working times and other details. Availability types can be regarded as different versions of a calendar, with which you can store multiple sets of working times into a single calendar. Therefore categorize the availability of resources according to different activities. For more information, refer to Availability types. Implementation phase During implementation of ERP LN, you must define the following basic calendar data: Availability types Working hours types The standard calendar The company calendar You have the option only to define a standard calendar in the Standard Calendar (tcccp0140m000) session and to specify a company calendar in the Companies (tcemm1170m000) session, but this limits your planning facilities. As the complexity of your business structure increases, more calendars with multiple availability types and working hours types are required. If you share the calendar tables between companies of a multicompany structure, the first day of the week must be the same for all companies. If one company defines Sunday as first day of the week and another company chooses Monday, you cannot share the calendars. To display the first day of the week, use the Companies (ttaad1100m000) session. Calendar data For each working time interval within a date that you include in a calendar, you can specify: Start time and end time Working hours type (optional) Efficiency factor Capacity percentage Overtime Related topics Overview of calendars and periods To set up the calendar structure Calendar hierarchy Availability types Efficiency factors Capacity percentage To use calendars |
