The schedule status files are used to store the record percentages at a number of fixed points during the schedule. These percentages are stored for each activity, in each record in the main database, and they represent the remaining percentages. The table below shows when the schedule status is stored and the corresponding name of the schedule status files.

 

 

The schedule status files are used to speed up the scheduling process. For example, if a change is made to the preschedule table, XPAC will use the schedule status at the end of the mined out quantities and then update the schedule from that point in time. This means that the initial mine status does not have to be recalculated and then updated with the mined out quantities.

If any of these schedule status files are accidentally deleted, XPAC will use the previous valid schedule status file to recalculate the schedule. If none of the schedule status files exist then XPAC will create them by recalculating the entire schedule from the start.

Note that there is only one set of schedule status files for the project and they refer to the active scenario. If you change the active scenario then XPAC will flag the schedule status files as invalid. In this case the schedule for the new active scenario will be recalculated from the start.
