ALV Grid

Former Member — Thu, 24 May 2007 19:04:52 GMT

I have a grid embedded in a custom control. I have

inserted some code in a PBO event to modify

several column attributes of the grid. The code

does not throw any exceptions, but the changes are

not reflected in the rendered grid.

Cant say much about the error without seeing the code, but it is not activating somehow, so best will be refer to any BCALV_* report in SAP only and check for it.

Amit

Usually we used to modify the fieldcatalog for changing the attributes. Are doing the same ?

Here is some of the code in the PBO.

data salv_columns type ref to cl_salv_columns_table.

data salv_column type ref to cl_salv_column.

salv_columns = processed_salv_table->get_columns( ).

TRY.

salv_column = salv_columns->get_column( 'LINE_NUMBER' ).

salv_column->set_visible( if_salv_c_bool_sap=>false ).

salv_column->set_technical( if_salv_c_bool_sap=>false ).

CATCH cx_salv_not_found.

ENDTRY.

Ah, yes the ALV Object Model. Excellent.

Your coding actually work pretty good in my system. Can I see the rest of the program?

Is LINE_NUMBER the correct name for the field?

As you can see in this simple example program, the setting of the attributes works fine. I have a screen 100 here with a single container in the dynpro called "CONTAINER'.

I have used the code in another application with no problems.

The problem arises when putting the grid

into a container. The grid is created in the PBO event, and I have

tried setting the column attributes inside the same PBO event, but

with no luck.

I have stepped into the code and see that the changelist is properly

updated with the coded requests. I have also tried putting the requested

changes in a PAI event just to test it. But again no luck here either.

Hmmm, intesting. Work good for me. What release and SP level are you at?

I think it has to do with this:

I am not using a table from the dictionary. Instead I am defining my own

table type within code.

And I believe there is some parameter that needs to be set to identify

the table as not coming from the dictionary.

I will do some more looking, but I am pretty sure this is the problem.

Thanks for the code. Everything works fine now.
