For each document number interval, you must specify a validity limit (year value).

You can define the same number range for several fiscal years (see following illustration). After changing fiscal years, the system starts assigning numbers again from the lower limit of the interval. The same document numbers are assigned in each fiscal year, but are uniquely identified by the year specification.

If you do not want to have numbers assigned based on each year, you must specify a year which lies far into the future, for example "9999". Documents are then assigned numbers from an interval that is unaffected by changes in fiscal year (see the following illustration).


External number assignment is automatically year-specific. A unique number results from the document number and fiscal year. You can therefore reuse your number ranges for external number assignment in each fiscal year without having to define them based on the year.

To edit or display a document, you must specify the fiscal year in addition to the document number on the request screen if your system assigns numbers based on each year. You can also have the system automatically default the fiscal year. To implement this function, you must specify it for each company code.

The following overview shows the effects of defining different number ranges.
