Allow ledger posting is not enabled in the asset book.

Initially, I run create accounting for a specific asset book. Later I found out that the Allow ledger posting is not enabled in the asset book. I then enabled it and run Create Accounting again. The process was successful but no entries are transferred to GL. I checked Review Journal Entries and found out that the entries are stucked in SLA with Transfer to GL Status = Not Transferable. I even run Import Journals and Post Subledger Journal Entries but still no entries are being transferred to GL. How to fix this kind of issue?

Is there possibility to delete entries ?
