Adding PF-Status, Header and Footer in ALV using class CL_SALV

By Nagaraj Kalbavi, TCS

Introduction

We can develop ALV using different ways like using type pool SLIS or using the class Cl_GUI_ALV_GRID.

In this article we will see how we can add PF-Status, Header and Footer to the ALV which is developed using class CL_SALV .

Code Snippet

In this program we will see adding PF-STATUS, Header and Footer to ALV using a single class CL_SALV_TABLE.
