How the System Assigns Sequence Numbers

The system uses the following parameters to determine the next document sequence number:

Term	Definition
Installation Options	Determines whether document sequencing is activated at the system level.
Business Unit	Determines whether document sequencing is activated for a specific business unit.
Accounting Date	Determines the prefix of the document sequence number range.
Document Type	Determines journal type, journal code, the level at which the sequence number is assigned, and whether the sequence number is automatically generated or entered manually.
Ledger Group	Determines the sequence range based on the ledgers within the ledger group. If Keep Ledgers in Sync (KLS) is selected for a given ledger group, the document type, date, status and sequence will be assigned based on the values associated with the primary ledger. If KLS is not selected for a ledger group, each ledger receives a unique sequence number and may have a different document type.

If you create a document through background processing, the system assigns a sequence number based on the document that you predefined on the definition pages and SQR process request pages.
