May be someone could tell me some functionality to get this data?

Hi, Oliver!
Below you'll see how-to-guide which will provide a step-by-step solution.
It's 100% works like 'CRM_ORDER_READ' (both for buffered values & DB ones).
How-to guide - reading order categorization
1.     Create package ZCATEGORY (Categorization)
2.     Create new dictionary objects:
2.1.     Structure ZMDS_CATEGORIZATION_CAT ( u201CCategory from categorizationu201D) with fields:
CAT_GUID          type      CRM_ERMS_CAT_GUID
CAT_HI          type      CRMT_ERMS_CAT_HI
IT_CAT_CA          type      CRMT_ERMS_CAT_CA_BUF_TAB
IT_CAT_CA_LANG     type      CRMT_ERMS_CAT_CA_LANG_TAB
2.2.     Structure ZMDS ZMDS_CATEGORIZATION_CATS ( u201CCategories from categorizationu201D) with fields:
CATEGORY1          type      ZMDS_CATEGORIZATION_CAT
CATEGORY2          type      ZMDS_CATEGORIZATION_CAT
CATEGORY3          type      ZMDS_CATEGORIZATION_CAT
CATEGORY4          type      ZMDS_CATEGORIZATION_CAT
3.     Copy CL_CRM_CATEGORY_RUN_BTIL class to new ZMD_CL_CRM_CATEGORY_RUN_BTIL class. In newly created class do following:
3.1.     u201CPropertiesu201D tab: <Create instance> = 2 u201CGeneralu201D
3.2.     Change method u201CMAP_SUBJECT_TO_CATEGORYu201D to u201CPublicu201D
4.     Create new class ZMD_CL_CATEGORIZATION (Categorization processing).
4.1.     u201CPropertiesu201D tab: <Create instance> = 2 u201CGeneralu201D
4.2.     Define constants:
4.2.1.      C_LNK_TYPE_IS_CODE     Constant     Public     Type     CRM_ERMS_CAT_LN_TYPE     Default link type     'IS_CODE'
4.2.2.      C_OBJ_DDIC_CRM     Constant     Public     Type     CRM_ERMS_CAT_OB_DDIC     External object name     'SUBJECTCODECRM'
4.2.3.      C_TREE_TYPE_CAT     Constant     Public     Type     CRM_ERMS_CAT_HI_TYPE Kind     of link     'CAT'
4.3.     Create static public method u201CGET_ORDER_H_CATu201D with importing parameter IV_GUID (type CRMT_OBJECT_GUID = order GUID)  & exporting parameter ES_CATEGORIES (type ZMDS_CATEGORIZATION_CATS).
5.     Create report ZMDR_ORDER_CAT for displaying order categorization.
