In this tutorial we will learn how to apply colors to a column in ALV report using CL_SALV_TABLE.

To apply column color,

Get the list of all columns of ALV using GET_COLUMNS().
Choose a particular column by calling the method GET_COLUMN().
Apply color by using the method SET_COLOR().

Classes used: CL_SALV_TABLE, CL_SALV_COLUMNS_TABLE, CL_SALV_COLUMN_TABLE.

Create a program in SE38 and copy the below code.
