We can through a number of methods in the class CL_SALV_DISPLAY_SETTINGS set SALV display, this tutorial demonstrates how to set the title Zerbra style and set SALV, as follows:
1, a reference to calls get_display_settings get CL_SALV_DISPLAY_SETTINGS
2, the method set_striped_pattern () and set_list_header () call of class CL_SALV_DISPLAY_SETTINGS
CL_SALV_DISPLAY_SETTINGS of course there are many other ways, can be viewed through specific SE24, as follows:
Before SALV tutorial 2- add a standard status bar (status) was added based on the code method set_display_setting (), UML flowchart as follows:
The complete code is as follows:
