BackgroundSpecial Features of Web Dynpro ABAP Programming

 

There are some differences in programming Web Dynpro ABAP components to standard ABAP programming.

  • You cannot use lists, nor dynpro and control technology in Web Dynpro ABAP programming. For example,

    • CALL / LEAVE TO SCREEN

    • LEAVE TO LIST-PROCESSING

    • WRITE / ULINE / HIDE

    • MESSAGE

  • The program flow cannot be changed in Web Dynpro ABAP programming. You cannot use statements to exit the current session or to start a new one. For example:

    • CALL / LEAVE TO TRANSACTION

    • SUBMIT

    • LEAVE PROGRAM

  • You cannot use certain system commands in Web Dynpro ABAP programming. For example:

    • EDITOR-CALL

    • SYNTAX-CHECK/GENERATE

  • Functional enhancements of Web Dynpro components, such as methods and event handlers are called by Web Dynpro Framework. This fills all parameters. There is therefore no need to query the parameter interface.

    • IS SUPPLIED

    • IS REQUESTED

  • The integration of type pools and program includes is not supported in Web Dynpro ABAP programming.
