Execute Transactions

The following sample application shows how to use the Transaction class to execute an SAP transaction.

Execute SAP Transactions

To run SAP transactions from ERPConnect:

  1. Connect to the SAP system using R3Connection. Set the UseGui property to true.
  2. Create a transaction object using Transaction().
  3. Specify the SAP transaction code using TCode.
  4. Optional: add batch steps using AddStep.
  5. Launch the SAP GUI and execute the SAP transaction using Execute.

Tip

The installation package of ERPConnect includes the Transaction-Recorder tool. This tool records transactions and implements them to code, see Transaction-Recorder.

The following sample code executes the SAP transaction MMBE (stock overview):
