Missing data in ALV demo program(s)

If I run any of the demo programs whose names start with SALV_DEMO, the screens do not show any data.

Example for program SALV_DEMO_TABLE_SIMPLE:

Initial screen of SALV_DEMO_TABLE_SIMPLE

Missing data in SALV_DEMO_TABLE_SIMPLE

As you can see, there's no data, so impossible to play with sort, filter and so on.

How to add some data?

You have to read the comments at the beginning of the source code.

For instance, there is the following comment for program SALV_DEMO_TABLE_SIMPLE:

*    If the table ALV_T_T2 is empty, please create data for the demo
*    by running report BCALV_GENERATE_ALV_T_T2

The program BCALV_GENERATE_ALV_T_T2 will fill the tables ALV_T_T2, ALV_CHCK, ALV_TAB and ALV_CUR, based on some predefined constants and some random logic.

It should be sufficient to run the program with the default values:

Initial screen of BCALV_GENERATE_ALV_T_T2

By default, after the data has been inserted into the four tables, it displays the contents of ALV_T_T2:

Contents of table ALV_T_T2 by BCALV_GENERATE_ALV_T_T2

Most of SALV_DEMO* and BCALV_TEST* programs are based on these tables.

NB: other demo programs, like BCALV_GRID* or BCALV_EDIT*, are based on other tables like SCARR, SFLIGHT, etc., which are filled by another report, SAPBC_DATA_GENERATOR.
