Typically General Ledger users are secured by data access sets. Data access sets use primary balancing segment values to secure access to ledgers, ledger sets, and portions of ledgers. Payables users are secured
by business units.
For the Payables to General Ledger Reconciliation report:
General Ledger users can see general ledger data for the balancing segment values in their data access set. General Ledger users can also see the Payables or Oracle Fusion Subledger Accounting data for all
business units linked to the ledger.
Payables users can see the Payables and Subledger Accounting data for business units in their security definition. Payables users can also see general ledger data for all balancing segment values in the ledger.
