tv_data1 = tv->data.

IF tv_data1->prevselectedrowindex IS NOT INITIAL.

FIELD-SYMBOLS: <row1> LIKE LINE OF LV.

READ TABLE LV INDEX tv_data1->prevselectedrowindex ASSIGNING <row1>.

DELETE FROM ZZ07_LV WHERE LVID = <row1>-LVID.

else.

message = 'Tv is initial!!!'.

navigation->set_parameter( 'message' ).

ENDIF.

navigation->goto_page( 'anzeigen.htm' ).

ENDIF.

move this thread to BSP area.

is LVID is the key field of the internal table?

is ZZ07_LV an internal table or DB talbe?

Hi Raja,

I think that probably the problem is with this <row>. It doesn't realy rcognise the row....

Is there another way or why is like this what do think?

The Error is:

"500 SAP Internal Server Error

Fehlermeldung: Feldsymbol ist noch nicht zugewiesen. ( Abbruchsart: RABAX_STATE )"

This means something like: The field symbol has not been associated

change this line

FIELD-SYMBOLS: <row1> LIKE LINE OF LV.

FIELD-SYMBOLS: <row1> type any .

place and HTTP break point and analyze which line is causing error.

Hi Raja,

thank you very much.

I change it and now he tells me that in this case <row1>-LVID. row diesn't have this LVID any more beacuse is missing struktur.

Do you think he doesn't recognize this row and that why I can't delete the row.

Thank you very much

WHEN 'delete'.

IF tv IS NOT INITIAL.

message = 'Tv is not initial'.

navigation->set_parameter( 'message' ).

DATA: tv_data1 TYPE REF TO cl_htmlb_event_tableview.

tv_data1 = tv->data.

IF tv_data1->prevselectedrowindex IS NOT INITIAL.

FIELD-SYMBOLS: <row1> type any.

READ TABLE LV INDEX tv_data1->prevselectedrowindex ASSIGNING <row1>.

DELETE FROM ZZ07_LV WHERE LVID = <row1>-LVID.

else.

message = 'Tv is initial!!!'.

navigation->set_parameter( 'message' ).

ENDIF.

navigation->goto_page( 'anzeigen.htm' ).

ENDIF.

FIELD-SYMBOLS: <row1> type any ,

<field> type any .

READ TABLE LV INDEX tv_data1->prevselectedrowindex ASSIGNING <row1>.

assign component 'LVID' of structure <row1> to <field> .

if not <field> is initial .

DELETE FROM ZZ07_LV WHERE LVID = <field> .

endif .

Hi RAJA,

I think this is in the right direction, but is still not working. This is my code now. I implement your suggestion:But there is still error: 500 SAP Internal Server Error

Fehlermeldung: Feldsymbol ist noch nicht zugewiesen. ( Abbruchsart: RABAX_STATE )

That's mean that fielssymbol is not correct or something like that. Here is my code again:

WHEN 'delete'.

IF tv IS NOT INITIAL.

message = 'Tv is not initial'.

navigation->set_parameter( 'message' ).

DATA: tv_data1 TYPE REF TO cl_htmlb_event_tableview.

tv_data1 = tv->data.

IF tv_data1->prevselectedrowindex IS NOT INITIAL.

FIELD-SYMBOLS: <row1> type any , <field> type any .

READ TABLE LV INDEX tv_data1->prevselectedrowindex ASSIGNING <row1>.

assign component 'LVID' of structure <row1> to <field> .

IF not <field> is initial .

DELETE FROM ZZ07_LV WHERE LVID = <field> .

ENDIF.

navigation->goto_page( 'anzeigen.htm' ).

ENDIF.

Hi RAJA,

I tries to debugg, but it is not debugging my code. This code is written in eventhandler in the BSP and it is not reaching it. I tries couple times.

The error is stil the same like it was with the field.

Di you think is beacuase of the row? Probably is not understanding wich row...

Is there another way to delete this row..

Thank a lot for help.

Mariana

without debugging you wont find answer for this problem.

in se 80 go to utilities->settings->abap editor->debuggin->activate external debuggin.

now place a external break point at

IF tv_data1->prevselectedrowindex IS NOT INITIAL.

now execute the page and click on "delete button" which triggers the server event. the debugger should start now.
