如果parent和children equip 都成功的从ERP download到CRM里，但是CRM 的object structure里只能看到child equip，看不到parent equip，一种原因是object category里缺少relationship PRDIB, 见如下error message:
下面的report能够输入object category，打印出该category当前assign的所有relationship，并检查PRDIB是否已经assign:
REPORT ZPROD_CAT_CHECK_REL.
PARAMETERS: cat_id TYPE comm_category-category_id OBLIGATORY DEFAULT 'OBJ_0401'.

IF sy-subrc <> 0.
