Like Pete_UK said, we need to know how you're tracking Attendance and how you
want to 'collate' the data.
I built a system for a company to do this that may be more elaborate than
what you are looking for, but I'll describe it just in case it gives you some
ideas.
General files structure:
There is an AttendanceRecords folder
Under AttendanceRecords there are folders for each DIVISION in the company
Within each DIVISION folder there is are individual attendance files for
each employee. There is also a SUMMARY folder in this folder.
There is one sheet in each employee .xls file that has the 12 months of the
year in rows, with day of the month in columns. A "reason for absence" is
entered into a cell for any workday that the employee is not at work.
Reasons could be things like V for vacation, U for Unexcused, S for sick or
personal day off, T for tardy, L for left shift early and some others. No
reason that all of these sheets couldn't be in a single workbook - this
company just wanted separate files for each employee.
OK that single workbook/sheet gives a detailed view of an employees
attendance for any month of the year.
In the SUMMARY folder for that division, there is a file that uses some
macro code to examine the individual employee folders for that division and
give a summary by month, calendar quarter and year to date of all absent
days that are "unmitigated" - that is they didn't have a good reason such as
vacation or sick. This file gives management a quick look at the overall
picture for the division.
Way up at the top level, in the AttendanceRecords folder, there's a
CorporateSummary workbook that also uses macro code to get the contents of
the various division summary workbooks and provides the employee name and the
division they are in along with the monthly, quarterly and year to date
absence counts for each individual in the corporation.
Again, there's no reason, except for the size of the workbook, not to have
all of this information available in a single workbook: 550 individual
employee sheets, 1 additional sheet per company division, and 1 sheet to
provide the total corporate overview of attendance.
