我有一个要求，我必须从 CRM_ORDER_READ 中过滤 CHANGED_AT。
我使用动态查询如下：
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( ).
但是虽然有条目，但结果为空。
我找到了关于同一问题的博客，但没有一个解决了这个问题。查询是否正确？
或者有没有其他方法可以过滤 CHANGED_AT？
