there is a group of employees who enter their clock in / clock out in a monthly based excel sheet. this excel sheet is printed out by employee, manager signs it on paper and personnel department stores it on paper somewhere.
this is ok ....
now they want this "excel sheet inside SAP ESS" -> employee should enter clock in / clock out times on monthly(!) base, the monthly "sheet" should be approved via workflow from manager, etc..
as u said you will nt use sap time management for these employees ? where they can enter in sap tables ? how it will store store in 2011 infotype in standard it will store in TEVEN table ....if you upload it on monthly basis lets say it will store in one z table for all the employees and where will be the managers will get the workflow request for them for these employees ?
but they don't want to store information in SAP HR time management -> so no time events in IT 2011, etc.... as they don't use it for this group of employees, only for others.
at present where you are storing these employees data in your system as u said it shud not store in sap ? are you running payroll for those employees or not in your sap system ?
standard no way it is not possible .....you can go for full customised for this ...
