Managing and Executing Batch Input Transactions 
From Theobald Software
The class Transaction offers the possibility of executing SAP transactions in the foreground as well as in a background process. This technique is called Batch Input. By executing in a background process, you will be able to process mass data and transfer it to the SAP system. This technique is often used if no BAPI exists.
Another possibility is to jump directly to an SAP transaction from your .NET application. The example below covers this.
The user is able to enter a material number and the name of a plant. After doing so, she/he can click the button and the SAP GUI is launched with transaction MMBE (stock overview). A special tool, the TransactionRecorder, is also included in the installation package to record such transactions and implement them easily in you own program code.
Sample Coding
The code below shows how add batch steps with the method AddStep. It is important to set the UseGui property to true. The SAP GUI will be launched by the method Execute.
[C#]
private void button1_Click(object sender, System.EventArgs e) { // Reset the batch steps transaction1.BatchSteps.Clear(); // fill new steps transaction1.ExecutionMode = ERPConnect.Utils.TransactionDialogMode.ShowOnlyErrors; transaction1.TCode = "MMBE"; transaction1.AddStepSetNewDynpro("RMMMBEST","1000"); transaction1.AddStepSetOKCode("ONLI"); transaction1.AddStepSetCursor("MS_WERKS-LOW"); transaction1.AddStepSetField("MS_MATNR-LOW",textBox1.Text); transaction1.AddStepSetField("MS_WERKS-LOW",textBox2.Text); // connect to SAP r3Connection1.UseGui = true; if (r3Connection1.AskUserAndOpen(true)) // Run transaction1.Execute(); }
[VB]
Private Sub button1_Click(ByVal sender As System.Object, _ ByVal e As System.EventArgs) Handles button1.Click ' Reset the batch steps transaction1.BatchSteps.Clear() ' fill new steps transaction1.ExecutionMode = ERPConnect.Utils.TransactionDialogMode.ShowOnlyErrors transaction1.TCode = "MMBE" transaction1.AddStepSetNewDynpro("RMMMBEST", "1000") transaction1.AddStepSetOKCode("ONLI") transaction1.AddStepSetCursor("MS_WERKS-LOW") transaction1.AddStepSetField("MS_MATNR-LOW", textBox1.Text) transaction1.AddStepSetField("MS_WERKS-LOW", textBox2.Text) ' connect to SAP r3Connection1.UseGui = True If r3Connection1.AskUserAndOpen(True) Then ' Run transaction1.Execute() End If End Sub
The screenshot below shows the sample program in action.
If you only want to open the SAP GUI and execute a single transaction without adding several batch steps, it is sufficient to set the property TCode and execute.
