DEX Portal File Processing returns the following error:
Outlet Activity ID cannot be updated as the case has sessions attached to it.
This error occurs when a Case has previously been reported to DEX under an alternative funding source.
Change the Site/Funding Source for the record back to the original value. The Change Log for the case should provide the original value.
If the service offering has been changed, the original case should be closed and a new case created with the new funding source.
Contact CDS Support for assistance with migrating the sessions to the new case record.
