In SSCUI 102530 'Maintain Settings for Event-Based Revenue Recognition', under 'Assignment Rule' tab, choose relevant Assignment Rule,
the error message account is mapped as a deferrals/Accruals account under Event Based Revenue Recognition(EBRR) source.

From CE2105, with introduction of Parallel Accounting, revenue recognition postings are supported for paralell ledgers.
In the new G/L accounting, you can no longer make a direct posting to accounts managed on an open item basis when you use a particular ledger or ledger group.
In SAP Standard it is only possible to create ledger specific postings to non open item managed accounts. 
Because the account is managed on an open item and therefore cannot be directly posted to.

Kindly consider whether the open item management setting should be activated to this account,
if not and if there's no postings, you may consider to deactivate it via APP 'Manage GL Account Master Data',
or you may consider to change the relevant account number used in above configuration points and reprocess the errors in APP 'Manage Real Time Revenue Recognition Issues' again to regenerate the missing revenue postings.
