Editable ALV Grid...

Former Member — Thu, 09 Oct 2008 11:20:32 GMT

Hi,

i am working on Module a module pool program. There is one ALV grid which is editable. It has three columns. 2 for checkbox and one input enable field. How to capture the changed internal output table.

I am using this code....

CALL METHOD W_ROGRID->CHECK_CHANGED_DATA.

I am getting runtime error after this statement is getting executed.

The error is 'Field Symbol has not yet been assigned'.

Can anyone tell me why i am getting this error.

Thnx

Hi mohammed,

In order to reply to your question here not in someone's else post.

You need additionally register the event. I forgot about this, sorry my fault.


"register edit events
      CALL METHOD W_ROGRID->register_edit_event
        EXPORTING
          i_event_id = cl_gui_alv_grid=>mc_evt_modified.

Now it should work.

Regards

Marcin

the error is coming from the fieldcatalog. are you editing the quantity/currency fields. if you have some quantity and currency fields you have to mention some important details in the fieldcatalog.

CFIELDNAME "currency unit ex: MEINS

QFIELDNAME " Quantity unit ex: WAERS

REF_FIELD " Quanity/currency field " EX: KWMENG / NETWR

REF_TABLE " Table ex: VBAP

Marcian,

Please find these piece of codes....

CREATE OBJECT w_alv_event.

CALL METHOD W_ROGRID->register_edit_event

EXPORTING

i_event_id = cl_gui_alv_grid=>mc_evt_modified.

SET HANDLER w_alv_event->cell_changed FOR w_rogrid.

No change in the output with this piece of code.....The method cell_changed is not getting triggered.

CREATE OBJECT w_alv_event.

SET HANDLER w_alv_event->cell_changed FOR w_rogrid.

CALL METHOD W_ROGRID->register_edit_event

EXPORTING

i_event_id = cl_gui_alv_grid=>mc_evt_modified.

No change in the output with this piece of code.....The method cell_changed is not getting triggered.

I am writing the above code in PAI event.

****************************************************************

CALL METHOD W_ROGRID->register_edit_event

EXPORTING

i_event_id = cl_gui_alv_grid=>mc_evt_modified.

If i call the above method in the PBO event then i am getting runtime error as soon as i click on one of the checkbox of my ALV grid.

the problem is with the checkbox. i am sure. show your fieldcatalog and layout code. the error is from there. are you using the layout-box_fieldname..?

just mention the fieldname related to checkbox and sequence number and see how it works.

just go to Your Control panel which is on the top right corner . if you wish to convey some message how you resolved then post the comment when you are trying to close the thread. if you don't have anything to say just silently close the thread by marking the thread as answered.
