Oracle EPM Data Exchange Integration Failure: "Invalid Period" Error After Update

I am performing a data load from an Oracle EPM Consolidation environment to an Oracle EPM Planning environment through Data Exchange. On Friday, June 19, 2026, the integrations between the two environments were working correctly; however, we understand that an update was carried out by Oracle, and now the integrations are no longer functioning.

The error generated in the log shows "Invalid period". However, in the integration configuration, we do not have the Period column assigned, since when executing this type of integration from the source environment (FCCS), a .dat file is generated with a multi-column format, which is then transferred to Planning.
