| | Workdays and calendar days in Enterprise PlanningSeveral types of
horizons, time fences, and lead times are expressed in workdays. During the planning process, these workdays need
to be translated to calendar days. When Enterprise Planning translates workdays to calendar days, it takes the capacity of the appropriate
calendar into account. Procedure for lead-time data For lead-time data (such as the safety time), the procedure
can be described as follows: - Enterprise Planning converts workdays to working hours, based on the basic capacity of the resource involved
(defined in the Resources (cprpd2100m000) session). If no resource is involved, the conversion is based on the basic
capacity of the work center (defined in the Work Centers (tirou0101m000) session).
- Enterprise Planning plans the working hours according to the resource calendar or
a more general calendar.
Procedure for horizons and time fences For horizons and time fences, the procedure can be
described as follows: - Enterprise Planning converts workdays to working hours, based on the basic day
capacity that is defined in the Planning Parameters (cprpd0100m000) session.
- Enterprise Planning plans the working hours according to the calendar of the
item's enterprise unit. If no enterprise-unit calendar is available, the
company calendar is used.
- The resulting time indications (expressed in hours, minutes,
and seconds) are rounded to the end of a plan period. (This step is not carried
out for signal horizons.)
Example: time-fence calculation The capacity defined
in the enterprise-unit calendar is displayed in the following table: | Date | Working times | Capacity [hrs] |
|---|
| June 10 | 6:00 A.M. - 6:00 P.M. | 12 | | June 11 | 6:00 A.M. - 6:00 P.M. | 12 | | June 12 | 6:00 A.M. - 6:00 P.M. | 12 | | June 13 | 6:00 A.M. - 12:00 noon | 6 | | June 14 | - | 0 | | June 15 | - | 0 | | June 16 | 6:00 A.M. - 6:00 P.M. | 12 | | June 17 | 6:00 A.M. - 6:00 P.M. | 12 |
Basic day capacity:
12 hours per day Current date: June 11, 4:00 P.M. Time fence: 3 workdays Procedure The time fence is
converted to the number of hours, minutes, and seconds, based on the basic
capacity (time fence = 3 x 12 = 36 hours). Then, the time fence
is planned forward, starting at the current date and time. This is illustrated
in the following table: | Date | Working times | Capacity [hrs] |
|---|
| June 11 | 6:00 A.M. - 6:00 P.M. | 2 | | June 11 | 6:00 A.M. - 6:00 P.M. | 12 | | June 11 | 6:00 A.M. - 12:00 noon | 6 | | June 11 | - | 0 | | June 11 | - | 0 | | June 11 | 6:00 A.M. - 6:00 P.M. | 12 | | June 11 | 6:00 A.M. - 6:00 P.M. | 4 |
The resulting time
fence is: June 17, at 10:00 AM. This time fence is rounded to the end of the
plan period in which it falls. | |
