Table is not getting displayed by using set_table_for_first_display

[former_member598310]

Hi All,

I am creating one simple alv output using oops concept.But not getting the table as output.Please find the below code and help me in finding the solution.

SPAN { font-family: "Courier New"; font-size: 10pt; color: #000000; background: #FFFFFF; } .L0S31 { font-style: italic; color: #808080; } .L0S32 { color: #3399FF; } .L0S33 { color: #4DA619; } .L0S52 { color: #0000FF; } .L0S55 { color: #800080; } .L0S70 { color: #808080; }

Hi Rajashree,

1. You need a screen (100 for example) with a container named "Container". In PBO of the screen you need call the method alv_display of your local class.
2. If you use local class you should have a method to create fieldcatalog instead of using subroutine.
3. You should work on the naming of your variables

Here is a working sample of your code:

Perhaps you can use CL_SALV_TABLE to display a report.

Check BCALV_GRID_DEMO for reference or search BC*ALV* in SE38 for the examples and valdiate it with what you have coded.

Thanks Nabheet ..Surely will check ..

[former_member598310]

Problem solved..Everything was right ..I had not place the custom control in the layout screen.Now its working .. Thanks all of you ..
