If SV TP Commit Status is equal to CO TP_IN_TRANSACTION, then the transaction has been started, but no Commit Transaction or Rollback Transaction system function has been called yet.

If the last transaction is Commit Transaction, then the commit has succeeded and all database operations have been committed. The last transaction action can be either Commit Transaction or Rollback Transaction. If SV TP Commit Status is equal to CO TP_ACTION_SUCCESS, then the last transaction action has succeeded. If the last transaction is Rollback Transaction, then the rollback operation has failed. If the last transaction is Commit Transaction then the Commit Transaction has failed and no database operation has been committed. If SV TP Commit Status is equal to CO TP_ACTION_FAIL, then the last transaction action has failed. It may contain one of the four valid values: This system variable tells you the status of the Commit Transaction or Rollback Transaction call. You should only use this system function when absolutely necessary. The EnterpriseOne will end the transaction without committing any database operations started between the Begin Transaction and Rollback Transaction calls. Use the same variable as used in Begin Transaction. This system function takes a MathNumeric type parameter called Transaction ID.

The example below shows how to use transaction processing through Event Rules:Ĭall this system function to cancel all the database operations started since the Begin Transaction and the End Transaction.
Transaction processing system companies code#
The transaction boundary must be just big enough to include all relevant database operations and not too large that it blocks other code from accessing the same database records. You need to carefully define the location of the Begin Transaction and Commit Transaction calls. There is no need for Event Rules (ER) to call Rollback Transaction after Commit Transaction. If the Commit Transaction fails, EnterpriseOne automatically rolls back the database operations so that none of the database operations will be committed. You can use the same variable as the one used in Begin Transaction system function.ĮnterpriseOne will commit all database operations started between the Begin Transaction call and the Commit Transaction call. Similar to Begin Transaction, this system function takes in a Transaction ID parameter. On Advanced Options, click the Include in Transaction option, and then OK.Ĭall the Commit Transaction system function to commit all the database operations started since the Begin Transaction call. On Data Source, click the Advanced Options button. On Insert Table IO, in the Advanced Operations section, select Open, and then click Next.

To include the Table I/O statements in the current transaction.Ĭlick the system function you have assigned to the event rule. This is because at any one time, only one transaction can be started from Event Rules.Īfter calling the "Begin Transaction" system function, the report can use Table I/O statements or Business Functions to conduct database table operations. Even though you must pass in a value for Transaction ID, the value is not currently being used by the system. You can use a Report Level Math Numeric variable to pass into the Transaction ID parameter. This system function has one MathNumeric type parameter named Transaction ID. Calling this system function initiates the beginning of the table updates that are part of the transaction.
