Difference between Internal and External Number Range in SAP

Each master record has a unique number in SAP.SAP needs it to display or change the

master record and to post to the vendor account.

Number ranges in SAP can be assigned with a internally or externally generated

number by the user. While defining the range in SAP this option can be selected to let

the system decide the number range to be selected while creating the master data;

Internal Number range in SAP

If you select this option then the document number will be generated by SAP

automatically in serial order within the range that you have selected while de￱ning

the

number range and will allot the next available progressive number to the next data

created. This option is selected to reduce the manual involvement of the user. The

number must be numerical.

External Number Range in SAP

While creating a master data you need to enter a number manually. With external

number range option in SAP, system will not automatically insert a number to the

document or master data. User can pick it randomly. It can be alphanumeric. Entering

the document number manually for each SAP ñnancial posting is time consuming and

risky to book transactions.

A number range can either be created as year dependent or year independent. For

year-dependent, a document number range has to be deñned for each new

accounting year as a year-end activity. You can deñne it as year independent by keying

9999 in the Year column.
