ALV with grid->set_table_for_first_display

[ronaldo_aparecido]

Hi Experts.

I'm working with  grid->set_table_for_first_display to develop ALV in module pool .My question is:

I can´t use 'REUSE_ALV_FIELDCATALOG_MERGE' to create my fieldcat what function  can i use compatible with grid->set_table_for_first_display

to create my fieldcat ?

Thansk for help.

You could try LVC_FIELDCATALOG_MERGE.

On the long run, you may be better using CL_SALV_TABLE=>CREATE as you just don't have to create the field catalog.

create field catalog as below

it_fcat   TYPE lvc_t_fcat, (Table Type ALV control: Field catalog)

wa_fcat   TYPE lvc_s_fcat (Structure ALV control: Field catalog)

assign the values to field catalog as below...

wa_fcat-row_pos = row.
wa_fcat-col_pos = col.
wa_fcat-fieldname = field.
wa_fcat-tabname   = tabnm.
wa_fcat-coltext = text.   you can add other properties also... like editable, drop down.. etc...

append wa_fcat to it_fcat.

then pass this field catalog to set_table_for_first_display as below..

CALL METHOD g_grid->set_table_for_first_display
     CHANGING
       it_fieldcatalog      = it_fcat
       it_outtab            = it_final.

Hi Ronaldo,

If you are using set_table_for_first_display method then you must have created container for it..

Once the screen is created there are two events created those are- PBO & PAI..

User Commands are handled in PAI event..

GOTO -> SE38 -> do F4 on BCALV* , you will get lots of examples.. SAP has covered all the topics related to ALV.. like tree, editable, etc.. etc..
