set_filter with NE option

Hi Experts,

I got stuck with one requirement where we need to preserve filter and everything is working fine with equal operator with below code.

typed_context->BTPARTNER->set_filter(

iv_attr_name = <lv_attr>

iv_value = <lv_value>

iv_filter_mode = IF_BOL_BO_COL_ITERATOR=>FILTER_MODE_INTERACTIVE ).

typed_context->BTPARTNER->build_table( ).

But I am unable to find an option where "Not equal" operation is not working.

Please suggest.

Thanks,

NJ
