ALV Grid Using Methods-handle_top_of_page

Former Member

riends please explain how to resolve the below issue.

I am working on ALV Grid using methods & trying to display

page heading using handle_top_of_page event.

I have defined & implemented the above method and in the implementation I have

given a write statement, which has to be displayed on the top of page.

I have also set the handler for top of page.

The program does not have any errors, but top of page event is not triggered, what might be the problem.

Regards,

Usha

Hi,

Did you used the following?

CALL METHOD DA_GRID1->LIST_PROCESSING_EVENTS

EXPORTING

I_EVENT_NAME = 'TOP_OF_PAGE'

I_DYNDOC_ID = DA_TOP

    • IS_SUBTOTTXT_INFO =

    • IP_SUBTOT_LINE =

    • CHANGING

    • C_SUBTOTTXT =

.

Check this link.

http://www.sap4.com/codigo-155.html

Check for some standard program to display the top-of-page.Sometimes,it may be GUI problem.So it won't display top-of-page.If it is GUI problen,you cannot see the program name box in SE80.

Check also whether that corresponding form is triggered in Debugging by placing a break-point inside the form.

Hope this helps.

Hi,

it may be because of your GUI. Try to run the same program in some other system.

Hi Usha,

Please try to run any program having a top of page event on your system. If its not displaying, then the problem is with your system's SAP GUI.

Otherwise, we have to see again.

Check these links, if they giv u some tips.

Meanwhile we shall try to find alternate sols for this.

Top-of-page event is for printing the ALV list. You should be able to see the header in report printout.
