SAP Transactions: Definition

 A transaction in SAP is like a program in normal computer languages, and is identified by a four-character transaction code. A transaction can be initiated directly from the command field on the presentation interface or from the corresponding menu option. There are two kinds of transactions: report and dialog transactions.

  • Report transactionsare SAP programs that collect selection parameters from the selection
    screen followed by the output called the lists.
  • Dialog programs consist of more than one interactive screen called a dynpro. These transactions sometimes also need preselected information for triggering them, not unlike the explicit selection screens in report programs; these are called parameter transactions.
