Document type and Number range relationship in SAP

Document Numbers, uniquely identifies every transaction within a fiscal year in a company code.

Number ranges for a document type in sap are used to define how numbers can be assigned to a transaction.

For every number range, following things must be specified.

• A two-character code
• Period until when the number range is valid
• An interval from which the numbers are chosen and
• Whether the number range is used in internal or external number assignment

Intervals for number ranges must not overlap.

Since transactions are kept for an indefinite amount of time, one has to define intervals that are large enough to handle this factor. Following system features ensure that number intervals are large enough:

• Number ranges can be defined for each company code. Thus, each company code can use the same number interval.
• Numbers can be up to ten characters long.
• Number ranges can be defined for each fiscal year.

All the number ranges will be Year Dependent. That means every year new number ranges has to be maintained in the system.

A number range is specified for each document types in SAP to generate a unique number which can be refereed always to track back the original transaction.

Each transaction number is selected from this number range. One number range can be used for several document types.
