Calendars in Enterprise PlanningIn other words, Enterprise Planning uses calendars to:
Calendar selection for production planning If LN cannot find a calendar, it uses the following priority path to select a calendar for production planning:
If the required delivery date of a planned production order is after the latest date on the calendar that is used for production planning, LN falls back on the workweek. For planning aspects that take place at a resource, Enterprise Planning uses the calendar that you linked to the specific resource. If no resource calendar is available, Enterprise Planning looks at the department calendar for planning. For planning aspects that take place at a work center that is not a resource, Enterprise Planning uses the calendar that you defined for the department in the Departments (tcmcs0565m000) session. For planning aspects that are not related to a work center, for example, fixed lead times, Enterprise Planning uses the calendar you defined for the enterprise unit to which the item in question belongs. Calendar selection for purchase planning For purchase planning, LN first determines the business partner safety time, for which a calendar is selected according to the following priority path:
Next, LN distinguishes between situations in which you specified a supplier in the Buy-from Business Partner field in the Items - Purchase (tdipu0101m000) session or in the Items - Purchase Business Partner (tdipu0110m000) session, and situations in which you did not define a supplier. Purchase planning with supplier If you specified a supplier, LN further distinguishes between items it can plan in the lead-time horizon and items that it cannot. For items that can be planned in the lead-time horizon, the next step LN performs is to offset the transport time. To do so, LN selects a calendar according to the following priority path:
Finally, LN must offset the processing time of the purchase order. The calendar to calculate this lead-time type is selected according to the following priority path:
For items that Enterprise Planning cannot plan in the lead-time horizon, LN must offset the calculated lead-time, for which LN uses the company calendar. Purchase planning without supplier If you did not specify a supplier for the item, after the offset of the outbound time, the inbound time, the extra lead time, and the safety time, LN only must offset the item supply time. To do so, LN uses the company calendar. Calendar selection for distribution planning For distribution planning, Enterprise Planning uses various distribution-related calendars. To offset the inbound time and the outbound time, LN uses the following priority path to select a calendar:
Next, LN offsets the extra lead time and the item safety time, for which the following priority path is used:
For the next step, LN checks whether you specified a carrier in which case LN offsets the transport time. To do so, LN uses the following priority path to select a calendar:
If you did not specify a carrier, LN checks whether you specified a resource in the Supplying Relationships (cprpd7130m000) session, in which case LN calculates the distribution supply time. To do so, LN uses the following priority path to select a calendar:
If you did not specify either a carrier or a resource, LN also calculates the distribution supply time. However, if you did not specify a resource, LN uses the following priority path to select a calendar:
