Filter CHANGED_AT from CRM_ORDER_READ

[former_member204556]

Hi Experts,

I have a requirement wherein I have to filter CHANGED_AT from CRM_ORDER_READ.

I used the dynamic query as follows:

lr_core = cl_crm_bol_core=>get_instance( ).
lr_core->load_component_set( 'ONEORDER' ).

lr_qs ?= cl_crm_bol_dquery_service=>get_instance( 'BTQSrvOrd' ).

lr_qs->set_query_parameters( lt_param ).

lr_qs->ADD_SELECTION_PARAM( iv_attr_name = 'CHANGED_AT'
iv_sign = 'I'
iv_option = 'GT'
iv_low = '20171127000000' ).

lr_result = lr_qs->get_query_result( ).

But the result is null though there are entries.

I found the blogs regarding the same issue but none solved the issue. Is the query correct?

Or is there any other way to filter CHANGED_AT?
