In this tutorial, we will add TOP OF PAGE in ALV report created using factory class CL_SALV_TABLE.
To add Top Of Page to the ALV report,
- we need to create instance for the class CL_SALV_FORM_LAYOUT_GRID.
- Create Label and Text to add content to the Top Of Page.
- Call the method SET_TOP_OF_LIST to set the Top of page.
Let see with an example. Create a program in SE38 (ABAP Editor) and copy the below code.
