I hope you have declared 'm_helper' in the attributes tab.

m_helper RefTo IF_WD_SELECT_OPTIONS.

Hi,

You have used the following code:

wd_this->m_helper->add_parameter_field( i_id = `CARRID` i_within_block = `BL01` it_result = lr_field ).

add_parameter_field method doesn't have the parameter named 'it_result'.

Regards
