Internal transactions are started always when a write operation on the database is performed and include all activities to guarantee the database consistency. Moreover, the application may react on a DBP_Store event in order to perform actions for ensuring the logical database consistency. Thus, write activities on a database may have several consecutive write operations that perform subordinated internal transactions. When one of these transactions has been failed, the whole internal transaction will be canceled. For more detailed error information about the errors detected check the error.lst file.

When running an application server, storing the transaction the replication server may have failed.
