如何获取特定服务票证的多级分类？

Question

您如何检索与特定服务票证关联的特定多级分类信息？ 例如，在这里我想检索“零售价”：

我需要将此信息显示在另一个屏幕中（票证搜索结果屏幕，以显示每张票及其动机和子动机）。

我仍然是 SAP CRM 开发的初学者，到目前为止，我只遇到了获取整个分类模式的方法，而不是与服务票证关联的特定值，或者只获取第一级类别的方法（本篇中的动机案子）。

Answer 1

你可以得到这样的类别：

1. 阅读服务票主题

   CALL FUNCTION 'CRM_SUBJECT_READ_OW' EXPORTING iv_ref_guid = iv_guid iv_ref_kind = 'A' IMPORTING et_subject_wrk = lt_subject_wrk EXCEPTIONS error_occurred = 1 OTHERS = 2.

2. 获取分类架构 GUID

    GET TIME STAMP FIELD DATA(lv_timestamp). SELECT SINGLE asp_guid FROM crmc_erms_cat_as INTO lv_asp_guid WHERE asp_id = lt_subject_wrk[ ref_guid = iv_guid ref_kind = 'A' ]-asp_id AND val_to >= lv_timestamp AND asp_state = 'R'.

3. 递归读取类别

   lv_cat_guid_new = lt_subject_wrk[ ref_guid = iv_guid ref_kind = 'A' ]-cat_id. DO 5 TIMES. " depending of how many category levels you have SELECT SINGLE node_guid FROM crmc_erms_cat_hi JOIN crmc_erms_cat_ca ON crmc_erms_cat_hi~node_guid = crmc_erms_cat_ca~cat_guid INTO lv_cat_guid_new WHERE crmc_erms_cat_ca~cat_id = lv_cat_guid_new AND crmc_erms_cat_ca~asp_guid = lv_asp_guid. IF sy-subrc <> 0. EXIT. ENDIF. ls_hier_query-tree_guid = lv_asp_guid. ls_hier_query-tree_type = c_tree_type_cat. ls_hier_query-node_guid = lv_cat_guid_new. CALL FUNCTION 'CRM_ERMS_CAT_HI_READ' EXPORTING iv_hier_query = ls_hier_query IMPORTING et_hier = lt_cat_hi. ls_categ_cat-cat_hi = lt_cat_hi[ 1 ]. lv_cat_guid = lt_cat_hi[ 1 ]-pare_guid. "For upper level cat. access INSERT ls_categ_cat INTO lt_categ_cat INDEX 1. * exit if root category level reached IF ls_cat_hi-pare_guid = ls_cat_hi-tree_guid. EXIT. ENDIF. ENDDO.

4. 输出

   LOOP AT lt_categ_cat INTO ls_categ_cat. CASE sy-tabix. WHEN 1. es_categories-category1 = ls_categ_cat. WHEN 2. es_categories-category2 = ls_categ_cat. WHEN 3. es_categories-category3 = ls_categ_cat. WHEN 4. es_categories-category4 = ls_categ_cat. WHEN 5. es_categories-category4 = ls_categ_cat. ENDCASE. ENDLOOP.

注意步骤3也可以通过cl_crm_ml_category_util类的方法实现

• cl_crm_ml_category_util=>get_cat_kids_all ( 片段)
• cl_crm_ml_category_util=>get_selected_category_tree (片段)
