Example Errors:

Error The build could not schedule course: [Course Number]: [Course Name] - The reason the course couldn't be scheduled is unknown. At least two conditions exist that can cause this error:

1. Make sure that the cited Courses' preference, if it has more than 1 period-per-meeting, has at least a matching number of valid start-periods checked.
2. The teacher(s) assigned to the course may be so heavily over-assigned that no amount of combinations could be found to build any sections.
Error The file room does not contain any valid data. Rooms are not set up to be scheduled. Verify that Use for Scheduling is selected on the Add/Edit Room page for all rooms used for scheduling.
Error The file course does not contain any valid data. Check the rank! Courses are not marked to be scheduled. Verify that Schedule This Course is selected on the Course Information page for all courses to be scheduled.
Error The file teacher does not contain any valid data.
Teachers are not marked to be scheduled. Verify that sure Schedule This Teacher is selected on the Staff Scheduling Preferences page for each teacher to be scheduled.
Error The file student does not contain any valid data. Students are not marked to be scheduled. Verify that Schedule This Student is selected on the Scheduling Setup page for each student to be scheduled.
Error The file tchasgn does not contain any valid data. The courses and number of sections of each course the teacher will teach has not been assigned. Add assignments for the teachers to be scheduled.
Error The file request does not contain any valid data. Student course requests have not been entered. Create course requests by manually adding requests on the students' Requests screen, using the Mass Add Requests function, utilizing an import, or setting up Student Request screens.
Error Invalid number of sections. The course is [Course Number]: [Course Name] , the section count is 0. The number of sections offered is not defined. To define the number of sections, navigate to PowerScheduler > Courses > Course Selection > scroll down to "Sections Offered" and populate a value.
Error Invalid term length found in the Course file. The course is [Course Number]: [Course Name] , the invalid term length is 0. The course does not have any terms associated with it. To associate terms, navigate to the Course Information page at: PowerScheduler > Courses > Course Selection > scroll down to "Valid Terms," click on the "Associate" button, select a term, click Submit, then submit the Course Information page.
Error Invalid course PPM found in the Course file. The course is [Course Number]: [Course Name] , the invalid course PPM value is 0 (must be > 0 and <= PeriodsPerDay). The course does not have a value for periods per meeting. To enter a value for periods per meeting, navigate to the Course Information page at: PowerScheduler > Courses > Course Selection > scroll down to "Periods Per Meeting," enter the appropriate value, then submit the page. For example, if the students attend the course for two periods, then enter 2 as a value.
Error Invalid course frequency found in the Course file. The course is [Course Number]: [Course Name] , the invalid frequency value is 0 (must be > 0 and <= DaysPerCycle). The course does not have a value entered for course frequency. To enter a value for course frequency, navigate to: PowerScheduler > Courses > Course Selection > scroll down to "Frequency" and enter the appropriate value.
Frequency is the number of times that a course meets during a cycle. For example, if there are four days in the cycle (A,B,C,D) and the course meets on all four days, then the frequency is 4. If the course meets every other day, then the frequency is 2.
Error Invalid meetings per cycle value found in the Course file. The course is [Course Number]: [Course Name] , the invalid value is 0. The course does not have value entered for "Periods Per Cycle." This number is calculated automatically by multiplying the Periods Per Meeting by the Frequency. If labs are included, then the formula is as follows: Periods per meeting multiplied by Frequency plus Lab Periods per meeting multiplied by Lab frequency = Periods per cycle. These settings are entered on the Course Information page at: PowerScheduler > Courses > Course Selection.
Info Invalid schedule type found in the Course file. The course is [Course Number]: [Course Name] , the invalid value is . The course does not have value entered for "Sched_LoadType" on the ScheduleCourseCatalogs table record for this course. This value is selected from a pull down list on the PowerScheduler > Courses > Course Selection page, with the options 'Standard', 'Lab', or 'LabFloat'. Verifying one of these selections are selected on the courses' preferences page then submitting this page will correct this error.
Error Invalid term length found in the Course file. The course is [Course Number]: [Course Name] , the invalid term length is 0. Valid terms have not been set up for the course. Associate valid terms on the Course Information page for each listed course.
Error The Student requests multiple times of the same course, but the course does not allow repeating requests. The student name is [Student Last, FirstName], and the course is [Course Number]. The named student has more requests for a course than the course currently allows. Delete extra requests so that the student has only one request for the course.
If students are permitted to enroll in a course more than once in the same term, select Allow Student Repeats in the Same Term on the Course Information page.
If students will be permitted to enroll in a course in more than one term, select Allow Student Repeats in Different Terms.
Error The Constraint file contains an invalid section. The constraint type is LabLink, the course number is [Course Number], the section number is 1. This constraint was ignored. Sections have been created either manually or during a previously imported build which have a Section Link constraint assigned to them. This can occur when a Block Term relationship is created for two courses while Building a schedule and the results of the Build have been imported. The courses will typically occur in pairs, though not necessarily consecutively in the Results Log list.
To correct this error, select the " Use locked master records" radio button on the Build Schedule page before executing the Build. This will result in the Build process continuing from the point of the last imported Build and will allow the sections and constraints previously built to remain intact. If it is desired to completely rebuild a previously imported schedule, the Section Link constraints must be deleted at: PowerScheduler > Constraints > Section Links.
Error Invalid section count found in the Course file. The course is [Course Number]: [Course Name] , the section count is 2, and the assignment section count is 0. The number of sections defined to be created for the course does not match the number of sections assigned to teachers who will be scheduled.
Error Invalid course found in the Course Link file. The course is [Course Number]. Error Invalid related course found in the Course Link file. The course is [Course Number], the related course (invalid) is [Course Number]. These related error messages indicate that a relationship assigned to the two courses is invalid. This is typically a result of different course setup parameters for the two courses. For example, the number of periods and/or days each course meets must be identical when using a Block Term relationship.
Error Invalid valid term found in the Course file (does not match the term length). The course is [Course Number]: [Course Name] , the course term length is 2.
Error The Teacher Assignment file contains an invalid course. The teacher is [Teacher Last, FirstName], the course is [Course Number].
Error The Teacher Assignment file contains an invalid term. The teacher is [Teacher Last, FirstName], the course is [Course Number] and the invalid term is 10-11. These error messages typically occur when an existing Master Schedule has been copied into a Build and Load scenario in PowerScheduler and a Build is attempted. To correct the errors, delete the copied Master Schedule or re-associate the valid terms on the Course Information page for each listed course.
Bitmap Errors
[Qty: 1, Rel: 10] Dropped because teachers could not use it (DropBmpTch) [Course Number]: [Course Name] - Crs [Number]:[Term] [Period(Day)],Crs [Number]:[Term] [Period(Day)],Crs [Number]:[Term] [Period(Day)]
Teacher Assignment Errors
[Qty: 1, Rel: 50] Teacher could not teach bitmap because that would make future courses fail to schedule. (FuturAssgn)[Course Number]: [Course Name]

** Advice **
suggest turning off future assignment checking for more information. If there is a Facility associated to that Course, make sure that the assigned teacher's room also has that Facility tied to it and that the room is set to 'Facility Use Only'. Otherwise, remove the Facilities preferences from both the Course and the Room.
Error Too many prescheduled constraints for teacher/course/section type. The teacher is [Teacher Name], the course is [Course Name], and the section type is [Section Type].
  • Only one Pre-Schedule constraint should be used for the same teacher, same course, and same section type.
  • Try removing the Section Type from the section and the constraint, and run the build again.
Error Invalid day found in the Course file. The course is [Course Number]: [Course Name], the invalid day is MW,TW,WW,HW,FW,MB,TB,WB,HB,FB. Use the internal day ID when specifying the course Valid Day Combinations, as opposed to using the Name or Abbreviation. Check here to view the days setup: Start Page > PowerScheduler > Days.
Error Invalid Term code found in the Course file. The course is [Course Number]: [Course Name], the invalid code is Y12-13. Verify the terms here: Start Page > PowerScheduler > Years & Terms, and re-associate the Year term to the course. The result should be Y1 or 12-13, but not Y12-13.
Error There is No Room To Host The Course Due to Course Max, Facilities or Department. The course is [Course Number]: [Course Name].
  • Navigate to Start Page > PowerScheduler > Rooms, and verify that Use for Scheduling is selected for the appropriate rooms.
  • Navigate to Start Page > PowerScheduler > Courses, and verify that the Maximum Enrollment is not set to 0 in the Course Information page.
  • Verify which Department and Facilities are associated to the course: Start Page > PowerScheduler > Courses. Then navigate to the room in which the course is being taught: Start Page > PowerScheduler > Rooms, and associate the Department and Facility to this room.
Error The schedule in the prescheduled constraint for course does not match the course parameters. The course is [Course Number]. The schedule expression is [Expression], term [Term]. Constraint dropped. The number of periods selected in the Pre-Schedule constraint do not match the value of Periods Per Meeting for the course. Check the value for Periods Per Meeting on the Course Information page: PowerScheduler > Courses > (select course), and then update the identified constraint accordingly. For example, if the Periods Per Meeting value is set to 1, set up the constraint for one period only.
Each Pre-Schedule constraint should correspond to a single section; i.e. if the school needs to pre-schedule five single-period sections of a course across five periods, create five Pre-Schedule constraints, where each constraint is associated with a single period. Do not create one single Pre-Schedule constraint for all five periods.
