For example I have a service request with the following two level's category maintained:
I use the following code to print out its subject value:
PARAMETERS: id TYPE crmt_object_id OBLIGATORY DEFAULT '8000000010'.
DATA: lv_guid TYPE crmt_object_guid,
ls_osset TYPE crmt_srv_osset_wrk.
SELECT SINGLE header_guid INTO lv_guid FROM crms4d_serv_h WHERE object_id = id.
IF sy-subrc <> 0.
WRITE:/ 'No service request found for id:', id.
RETURN.
ENDIF.
CALL FUNCTION 'CRM_SERVICE_OS_READ_OB'
EXPORTING
iv_ref_guid = lv_guid
iv_ref_kind = 'A'
IMPORTING
es_srv_osset_wrk = ls_osset.
LOOP AT ls_osset-osset ASSIGNING FIELD-SYMBOL(<osset>).
LOOP AT <osset>-subject ASSIGNING FIELD-SYMBOL(<subject>).
WRITE:/ |sort： { <subject>-sort }, ASP id: { <subject>-asp_id }, CAT id: { <subject>-cat_id }| COLOR COL_NEGATIVE.
ENDLOOP.
ENDLOOP.
Result
Why CA_4?
Only leaf value for category is stored for SERVICE_OS, which makes sense since all its parent in the hierarchy tree could anyway be derived.
