LocalTransaction 

From a Connection object (see Client Programming Model) you can receive a Transaction object which is bound to the actual Connection object. You can then start the transaction, execute several calls and end the transaction.

 

Example:

………………………………………………..

// allocate and start LocalTransaction

connection.getLocalTransaction().begin();

 

// create Interaction and Records, fill records with business data

………………………………………………

 

// execute first call

MappedRecord output1 = (MappedRecord)interaction.execute(null, input1);

 

// evaluate output1 and using it fill the new input2 with some data.

…………………………………………….

 

// execute next call

MappedRecord output2 = (MappedRecord)interaction.execute(null, input2);

 

// make some more calls, if needed

………………………………………………

 

// if all this calls were proceeded successfully, then commit LocalTracaction

connection.getLocalTransaction().commit();

// after commit, all statements written with update task in ABAP will be persistet

// in the target data base

 

// otherwise rollback it, by calling 

connection.getLocalTransaction().rollback();

// In this case all statements written with update tasks will be discarded.
