Function implementation ALV Table 1: The simplest ALV display

ALV has three implementation methods: cl_salv_table, cl_gui_grid_display, and function, they are reuse_alv_list_display and reuse_alv_grid_display. Currently, functoin is used to implement Alv. In fact, the underlying layer of these two functions is also based on the class cl_gui_grid_display.

 

Let's take a look at the differences between the two functoin implementations of ALV?

 

ALV effect implemented with reuse_alv_grid_display

 

ALV effect implemented by reuse_alv_list_display

In fact, implementing ALV is quite simple, mainly called the two functions. The following describes the implementation steps:

I, Declare the internal table of the content to be displayed and obtain data

Data: it_spfli type table of spfli.

Select * From spfli into Table it_spfli.

II, Call the function of ALV

Call function 'reuse _ alv_list_display'

 
Exporting

I _structure_name = 'spfli'

Tables

T_outtab = it_spfli.

Note: The function called here is reuse_alv_list_display. If you want to achieve the first effect, you should call

Use reuse_alv_grid_display. The two display effects are different and the operation methods are basically the same.

In this example, two parameters are used to call the function: I _structure_name and

T_outtab. I _structure_name is the structure of the output list, And t_outtab is the content of the output list.

 

Below are all the source code

Data: it_spfli type table of spfli.

Select * From spfli into Table it_spfli.

 

Call function 'reuse _ alv_list_display'

Exporting

I _structure_name = 'spfli'

Tables

T_outtab = it_spfli.
