Time Profile 
A time profile contains date specifications and instructions as to how you can enter date specifications. In the time profile, you specify the database read period, the evaluation period, the planning period and the date for dispatching the backlog. Please consider the following points:
- The system accesses all requirements lying completely or partially within the database read period.
- The evaluation period must be smaller than or equal to the database read period.
- The planning period must be smaller than or equal to the evaluation period.
If you have not entered a planning period then the system makes it the same as the evaluation period.
- All the backlogged capacity requirements up to the date for dispatching the backlog are dispatched. This gives you a summarized overview of backlogged operations. This date is used for the planning table (tabular form) or for displaying data per period.
You use the entry type to specify how you want to enter the limits for the periods or the date for dispatching the backlog. Typical entry types are calendar day or calendar month.
There are two different ways of entering the start and finish dates for the periods or the date for dispatching the backlog:
- Entry with firm date: In this case, you can enter the start or the end of the period directly. Typical entries for the month would be 03/95 and 05/95.
- Relative to the current date: Depending on the type of entry, you can refer to the current date. For example, if the type of entry is calendar days and the current date is 05/01/95, by entering -10 and 10 you specify a period of 10 calendar days before and after the current date.
