ALV GRID display using classes(oops) for calling a screen repeatedly

Former Member — Wed, 23 Dec 2009 11:32:44 GMT

Hi,

I am using screen 100 PBO module to display my list with some editable fields in my output using CALL METHOD g_grid->set_ready_for_input.

In PAI module I am cross checking the input fields and if there are any errors I am displaying those error records by again calling screen 100.

But the new data doesn't replicate in the needed output.ie., if there are 3 records in the main o/p list in that if, 1 record is in error, I should display only that 1 record with one more field at the end stating error message in the column. I have taken measure to inculde the extra field in the fieldcategory.

Please help me by telling me that how I should pass the screen controls to get the need list.

Regards

Mac

First check by debugging,that data is getting refreshed in u internal table.if data got refreshed,then u need check the container.

**Create Container ALV Grid

IF g_cust_grid IS INITIAL.

Create Control Container for Grid

CREATE OBJECT g_cust_container

EXPORTING

container_name = g_container.

CREATE OBJECT g_cust_grid

EXPORTING

i_parent = g_cust_container.

ENDIF.

**Displaying data in grid

CALL METHOD g_cust_grid->set_table_for_first_display

EXPORTING

IS_LAYOUT = g_wa_layout2

CHANGING

it_fieldcatalog = g_t_fieldcat

it_outtab = g_t_screen.

Raghu.

I have seen it in the debug mode, the data is not getting refreshed.

When the screeen is called for the second time, I have put an condition like

IF g_custom_container IS INITIAL.

PERFORM create_and_init_alv CHANGING t_dspdat[]

gt_fieldcat.

ENDIF.

here the condition is getting failed. Earlier when screen 100 is called t_dspdat[] has 3 records and when this same screen is called second time t_dspdat[] has 1 record, but displays 3 records only.

How should I refresh the data.

Any help.

Regards

mac

Hi Mac Mohan,

In the same class, with set_table_for_first_display, there is one more method called refresh_table or just refresh().

Try to do use this.

You have several options:

1) After the user hits enter and PAI/PBO gets triggered you need to execute a soft refresh to get the data reflected in your data table. Then you can make your checks and inform the user

2) You can implement the event handler on_data_changed of the grid. This way you can check field by field when ever a field changes in the grid. You can raise errors and this way set the focus to the wrong cell.
