* >>> Start from activity nr                                           *
* .......... convert activitynr > activity guid
CLEAR x_actguid.
SELECT single GUID FROM CRMD_ORDERADM_H
                    INTO X_ACTGUID
                    WHERE object_id = p_activ.
IF sy-subrc = 0.
* .......... convert activity guid > document ID
   CLEAR X_LOIO_ID.
   SELECT single LOIO_ID FROM SCMGRECP01
                         INTO X_LOIO_ID
                         WHERE PHIO_ID = X_ACTGUID.
   IF sy-subrc = 0.
* .......... convert document ID > Dossiers POID-ID
      CLEAR X_PDIR.
      SELECT single PROP08 FROM SCMGRECL01
                           INTO X_PDIR
                           WHERE LOIO_ID = X_LOIO_ID.
      IF sy-subrc = 0.
* .......... convert Dossiers POID-ID > Case nr
         CLEAR x_case_guid.
         SELECT single CASE_GUID FROM SCMG_T_CASE
                                 INTO x_case_guid
                                 WHERE RECORD_PDIR = X_PDIR.
         IF sy-subrc = 0.
            CLEAR x_case.
            SELECT single EXT_KEY FROM SCMG_T_CASE_ATTR
                                  INTO x_case
                                  WHERE case_guid = x_case_guid.
            IF sy-subrc <> 0. ENDIF.
