Hi,
I am using this method to set some defualt value to selection screen paramter in WebDynpro ABAP but it doesnt work , parameter comes up with a blank value.
wd_this->m_handler->SET_VALUE_OF_PARAMETER_FIELD( EXPORTING
I_ID = 'P_MXHITS'
I_VALUE = lv_mhits ).
This is coded in view's method WDDOINIT.
Thanks,
Krishna.
Hi,
Please use the below code to set the default value in the parameter field:
DATA : lr_value TYPE REF TO data.
FIELD-SYMBOLS : <fs_value> TYPE sflight-carrid.
CREATE DATA lr_value TYPE sflight-carrid.
ASSIGN lr_value->* TO <fs_value>.
<fs_value> = 'AA'.
CALL METHOD wd_this->lo_select->add_parameter_field
EXPORTING
i_id = 'CARRID'
i_value = lr_value
.
Regars,
MAdhu

Hi Mahdu
I have already tried the code you suggested, but it was throwing this dump.
Runtime Errors ASSERTION_FAILED
I found a few OSS notes that resolves this problem, so I implemented them and retried with code that you suggested and now it works perfectly.

The method being used is right.
Please check for the ID used in the method with the ID used in the method add_parameter_field.
Also, set a breakpoint and check the value of the variable 'lv_mhits', just pior to set_parameter method.

Hi Chinnaiya & Sharath,
DATA lv_50 TYPE i VALUE 50.
data : lv_mhits type ref to data.
create data lv_mhits type I .
append initial line to lt_params assigning <fs_params>.
<fs_params>-m_id = 'P_MXHITS'.
<fs_params>-m_WITHIN_BLOCK = 'B1'.
<fs_params>-m_value = lv_mhits.
<fs_params>-m_description = lv_text207.
*add to the selection screen.
wd_this->m_handler->ADD_PARAMETER_FIELDS( EXPORTING IT_FIELDS = lt_params )
get reference of lv_50 into lv_mhits. "this has value '50'.
*set default value
wd_this->m_handler->SET_VALUE_OF_PARAMETER_FIELD( EXPORTING
I_ID = 'P_MXHITS'
I_VALUE = lv_mhits ).
That is the code I wrote. Do you see any issues with it?
Thanks,
krishna.
HI Krishna Prasad ,
Go through the below sample code and make a try , hope it will work properly
def_value(2) type c value 'AA', " default value
lr_value type ref to sflight-carrid .
field-symbols: <value> type any .
* assigning default valu to the field symbol
ASSIGN def_value to <value>.
data d_value type REF TO data .
*assigning FS to the variable of type ref to data
CREATE DATA d_value type string .
get REFERENCE OF <value> INTO d_value. :d_valu will hold the defalt value now
wd_this->m_handler->add_parameter_field( "M_HANDLER type IF_WD_SELECT_OPTIONS
i_description = 'text'
i_id = 'PREDEF_PARAMVALUE'
i_value = lr_value ).
wd_this->m_handler->set_value_of_parameter_field(
i_id = 'PREDEF_PARAMVALUE'
i_value = d_value ).

Chinnaiya P
