Source codes are used to identify the origin of an entry. By inserting Source Code in the Journal templates, source code will be copied to all journal lines created under the journal template. This can help to trace the journal entries are posted from which journal.
To setup the Source Code, click FINANCIAL MANAGEMENT --> GENERAL LEDGER --> SETUP --> TRAIL CODES --> SOURCE CODES to open the Source Codes window. You can see all the source code defined in the system in this window. Select any source code and the click on the Source button and then select the relevant register to see all entries for the source code.
