Difference between PostTransactionNotice and TransactionNotification procedure
The only differences being when they are triggered and the ability to use the @error functionality of SBO_SP_TransactionNotification to rollback transactions. SBO_SP_PostTransactionNotice can only be triggered at the end of an action (transaction committed). Most users only use SP_TransactionNotification because it can be used to verify data to block unwanted posting.
