Document number range in SAP uniquely identifies every transaction within a fiscal year in a company code. These are used to define how numbers are assigned to documents.

Document number range in sap is a transportable configuration which can be transported by choosing Interval > Transport from the creation screen.

When you transport document number range in sap from a source system to a target system, the configuration present in the target system first gets deleted and the transported configuration takes place of that. For every document number range, the following must be specified.

  • A two-character code
  • Period until when (a year value) it is valid
  • An interval from which it will be chosen and
  • Whether it will be used as internal or external assignment

The document number range intervals should not overlap.

You can assign alphanumeric numbers to your document posting. This can be done by selecting external assignment selection from the creation screen.

Since documents may be kept in SAP for an indefinite amount of time, one has to define intervals that are large enough to handle this factor.  The following system features ensure that the number intervals are large enough:

  • It can be defined for each company code.
  • Document Number can be up to ten characters long.
  • Number ranges can be defined for each fiscal year.
