Guidelines for Transaction Numbering
Use the various options on the transaction source assigned to a transaction to manage your transaction numbering requirements.
Refer to these guidelines when defining transaction numbering for transactions assigned to specific transaction sources:
-
Document Sequences
-
Automatic Transaction Numbering
-
Copy Document Numbers to Transaction Numbers
-
Allow Duplicate Transaction Numbers
-
Credit Memo Transaction Source
Document Sequences
If necessary, define document sequences to assign unique numbers to each transaction, in addition to the transaction number assigned automatically.
Ensure that the necessary setups for document sequences are completed, according to your requirements.
Automatic Transaction Numbering
To automatically number new transactions you create using a transaction source, enable the Automatic transaction numbering option and enter a number in the Last Number field.
For example, to start numbering transactions with 1000, enter a last number of 999. Receivables automatically updates the Last Number fields on transaction sources, so you can review the transaction source later to see the last transaction number that was generated.
You can use automatic transaction numbering with both Imported and Manual transaction sources.
Copy Document Numbers to Transaction Numbers
If you're using document sequences and you want to use the same number as both the document number and the transaction number for transactions assigned to a transaction source, enable the Copy document number to transaction number option.
If you're using Gapless document sequences, you should enable this option if you require gapless transaction numbering. This ensures that transaction numbers are generated sequentially with no missing numbers.
Allow Duplicate Transaction Numbers
Enable the Allow duplicate transaction numbers option to allow duplicate transaction numbers within a transaction source.
This option is for manual transaction numbering only.
Credit Memo Transaction Source
Assign a credit memo transaction source to an invoice transaction source, if you want to number credit memos differently from the invoices that they credit.
