Hi demaauliansyah ,

REPORT z_display_table.

DATA: lv_table_name TYPE tabname,

lt_table_data TYPE TABLE OF (lv_table_name).

PARAMETERS p_table TYPE tabname.

IF p_table IS INITIAL.

MESSAGE 'Please enter a table name' TYPE 'E'.

ENDIF.

IF NOT cl_abap_dictionary=>is_table_known( p_table ).

MESSAGE 'Table not found' TYPE 'E'.

ENDIF.

SELECT * FROM (p_table) INTO TABLE lt_table_data.

cl_salv_table=>factory(

IMPORTING

r_salv_table = DATA(salv_table)

CHANGING

t_table = lt_table_data

).

salv_table->display( ).

In this example, we first prompt the user to enter a table name using the PARAMETERS statement. We then check if the entered table exists using the cl_abap_dictionary=>is_table_known method. If the table exists, we use a dynamic SELECT statement to retrieve all data from the table and store it in the lt_table_data internal table. We then use the cl_salv_table=>factory method to create an instance of the cl_salv_table class, passing in the lt_table_data internal table as the data source. Finally, we call the display method on the salv_table object to display the table on the screen.

Please edit your answer, select your code and press the button [CODE], which makes the code appear colored/indented, it will be easier for people to look at it. Thank you!

Hello vinaychowdary,

sure that your source code works? Not in mine... 2 problems:

1.: With this

DATA: lv_table_name TYPE tabname,
    lt_table_data TYPE TABLE OF (lv_table_name).

you intend to declare a table of a type that is not known at compile time. IMHO you have to use some RTTI mechanism to declare the table at runtime, when the table name is given.

2.: Class CL_ABAP_DICTIONARY does not exist (checked in some systems).

Kind regards

Another homework question?

Being spoonfed the answer won't help you in your new career.

[former_member844813]

yes i do know that, but if you provide me with some explanation, I learn at the same time that way.

Thank you for the reminder, appreciate it
