Reference https://docs.oracle.com/cloud/latest/projectcs_gs/OAPFM/OAPFM1125357.htm#OAPFM1125357 Assignment of Supporting References Supporting references may be used to capture transaction values on journal entry lines. A supporting reference can be used on a journal entry rule set only if it's assigned a source from the event class of the journal entry rule set.
Creating Supporting References: Explained
Supporting references are used to store additional source information about a subledger journal entry at the line level.
Supporting references with balances establish subledger balances for a particular source and account for a particular combination of supporting references plus the account combination.
For example:
If a journal line contains a supporting reference that includes two sources, Customer Type and Customer Name.
Balances are created for the account combination, plus customer name and customer type.
Examples of how you may want to use supporting reference balances are to:
Facilitate reconciliation back to the subledgers and source systems by tagging journal entries with transaction and reference attributes.
Create balances by dimensions not captured in the chart of accounts.
Reporting using dimensions not captured in the chart of accounts.

Profit and loss balances by dimensions not captured in the chart of accounts Define supporting references to hold additional supporting information for detailed account balance maintenance or reconciliation and reporting requirements.
