Former Member — Fri, 13 Jul 2007 04:13:22 GMT

I hve radio button in selection screen . if i executet his prog by selecting any of this radio button it shuld go to alv list. here alv list using the concept of oop.

whether i need to add 2 screens to display this 2 ALV list.since the method to display the ALV is writing in PBO output of the screen.

Hi Anu,

yes u can use the same screen, in PBO Passthe internal table to the method used for creating alv, based on the radiobutton pressed.

for ex:

if p_r1 = 'X'.

call method with itab1.

elseif p_r2 = 'X'.

call method with itab1.

endif.

but wat im doing is

if p_r1 = c_x.

PERFORM fieldcatalog_init.

perform alv_grid_class.

elseif p_r2 = c_x.

endif.

perform alv_grid_class this perform will call screen 100. so PBO will call automatically. so how can i pass itab.

Hi Anu,

what u could do is declare the internal table used in the screen 100 as global so that any screen in that program can use it. Once the radiobutton is pressed populate the inetrnal table you are using during creation of ALV and then call the fieldcatalog & alv_grid_class methods.

but in

MODULE PBO OUTPUT. (of the screen 100)

CALL METHOD GRID->SET_TABLE_FOR_FIRST_DISPLAY

exporting

I_BUFFER_ACTIVE =
I_BYPASSING_BUFFER =
I_CONSISTENCY_CHECK =
I_STRUCTURE_NAME =
IS_VARIANT =

I_SAVE = 'A'

I_DEFAULT = 'X'

IS_LAYOUT = gs_layout

IS_PRINT =
IT_SPECIAL_GROUPS =
IT_TOOLBAR_EXCLUDING =
IT_HYPERLINK =
IT_ALV_GRAPHICS =
IT_EXCEPT_QINFO =

CHANGING

IT_OUTTAB = t_output1[]

IT_FIELDCATALOG = w_gt_field

IT_SORT =
IT_FILTER =
EXCEPTIONS
INVALID_PARAMETER_COMBINATION = 1
PROGRAM_ERROR = 2
TOO_MANY_LINES = 3
others = 4

will call this method passing t_output1.

but for the next radiobutton internal table dat shuld pass to this method is t_output2.

can i pass internal table to module PBO output?

Hi,

do like this.

CALL METHOD GRID->SET_TABLE_FOR_FIRST_DISPLAY

exporting

I_SAVE = 'A'

IS_LAYOUT = gs_layout

CHANGING

IT_OUTTAB = t_output1

IT_FIELDCATALOG = w_gt_field[].

rgds,

Hi Anu,

If the structure of t_output1 and t_output2 is same then create a common internal table say t_output_common and pass this to the method. Populate this method once the radio butoon is clicked.

for ex:

if p_r1 = 'X'.

t_output_common[] = t_output1[].

//cal performs as above

elseif p_r2 = 'X'.

t_output_common[] = t_output2[].

//cal performs as above

endif.

NO itab structure is not same..

Re: ALV using class

Former Member — Fri, 13 Jul 2007 05:30:49 GMT

ok then what u can do is call this method

GRID->SET_TABLE_FOR_FIRST_DISPLAY itself based on radiobutton selected.

capture which radiobutton selected in the first screen and store it in a variable and in the screen 100. use that variable to trigger this method.

so based on radio button selected , will this GRID->SET_TABLE_FOR_FIRST_DISPLAY need to write twice??

Re: ALV using class

Former Member — Fri, 13 Jul 2007 05:39:43 GMT

yes u need to write it twice with diff based on radio button selected. but will be triggered only one based on radiobutton.
