An Oracle Fusion Cloud customer has a complex enterprise structure that includes multiple legal entities...

When balancing an intercompany journal, Oracle Fusion Cloud will first look for a primary balancing segment rule that matches the provider and receiver primary balancing segment values. If such a rule exists, it will be used to generate the intercompany receivables and payables accounts. If not, Oracle Fusion Cloud will look for a chart of accounts rule, then a legal entity-level rule, and finally a ledger-level rule. The primary balancing segment rule has the highest priority and the ledger-level rule has the lowest priority. References:
