Hi Rakesh,

You will have to pass IT_FIELDCATALOG parameter.

This can be populated through reuse_alv_fieldcatalog_merge function modules.

Hi Rakesh,

In the call to method set_table_for_first_display,

you are passing structure 'ZRAK' for fieldcatalog, ensure that this is not a local structure, this has to be available thru SE11, else you have to create a fieldcatalog & pass it to the method instead of passing the structure name.

Give the container name in upper case

Specify all these details, also specify 'CCONTAINER' in caps.

Hello Rakesh,

Is this your entire code or only a part of it?

You have to create a screen and then in the screen layout,make a custom container.Name it as CCONTAINER.

After data declaration and appending data to your internal table t_itab,call screen 100.

Write the code for creating the container,creating the grid and the method SET_TABLE_FOR_FIRST_DISPLAY in the PBO (status module) of the flow logic of the screen.

Also,in the create container instance,write the container name CCONTAINER in capitals.

Hello Rakesh,

Standard tool bar of the ALV??It ideally comes unless if you have programatically excluded the tool bar in SET_TABLE_FOR_FIRST_DISPLAY by passing a parameter ie.

CALL METHOD ALV->SET_TABLE_FOR_FIRST_DISPLAY

EXPORTING

I_STRUCTURE_NAME = 'SPFLI'

• IT_TOOLBAR_EXCLUDING = itab_ui.

Make sure you have commented this line :

• IT_TOOLBAR_EXCLUDING = itab_ui.

Also,have a look at this link:

<b>http://fuller.mit.edu/tech/controls_technology.htm</b>

Hi Sadiqulla,

can u plz explain in detail?

[Former Member]

Hi,

Actually standard toolbar is displayed automatically when u use

set_table_for_first_display.

The toolbar will not be displayed if u have populated the layout parameter with no_toolbar = 'X'.

In the below case i have populated the layout with no_toolbar = 'x' so i will not get the standard toolbar.

DATA: tool_layout TYPE lvc_s_layo,

tool_layout-no_toolbar = 'X'.

CALL METHOD grid1->set_table_for_first_display

EXPORTING

• i_bypassing_buffer = 'X'

• I_BUFFER_ACTIVE =

• I_CONSISTENCY_CHECK =

• I_STRUCTURE_NAME =

• IS_VARIANT =

• I_SAVE =

• I_DEFAULT = 'X'

is_layout = tool_layout

• IS_PRINT =

• IT_SPECIAL_GROUPS =

• IT_TOOLBAR_EXCLUDING =

• IT_HYPERLINK =

• IT_ALV_GRAPHICS =

CHANGING

it_outtab = it_TABLE

it_fieldcatalog = t_fcat

• IT_SORT =

• IT_FILTER =

• EXCEPTIONS

• INVALID_PARAMETER_COMBINATION = 1

• PROGRAM_ERROR = 2

• TOO_MANY_LINES = 3

• others = 4

Standard toolbar will also not be diaplayed if u have not commented IT_TOOLBAR_EXCLUDING in the function module

set_table_for_first_display

If it_toolbar_excluding is commented and u have not populated the layout with

no_ toolbar the toolbar comes automatically.

Regards,

Sruthi
