FM RH_STRUC_GET and buffer_mode

Question

Hi,
The FM RH_STRUC_GET offer an importing parameter called BUFFER_MODE. I have come across severel buffer modes i existing coding, like X, F and D.
My problem is that we are using the FM a lot. And I have a performance problem, that the FM doing a lot of identical selects on dababase.
Is there a place where I am able to get a list of all possible buffer modes, and som documentation on the differences of the modes.
Best regards,
Martin Molz

Hi Gilo,
Please check this example :
DATA: IOBJEC    LIKE OBJEC    OCCURS 0 WITH HEADER LINE,
        ISWHACTOR LIKE SWHACTOR OCCURS 0 WITH HEADER LINE,
        ISTRUC    LIKE STRUC    OCCURS 0 WITH HEADER LINE.
  CALL FUNCTION 'RH_STRUC_GET'
    EXPORTING
      ACT_OTYPE      = 'S'
      ACT_OBJID      = MGR_POS ---> <Position>
      ACT_WEGID      = 'ZSPS'     -
> Relation
      ACT_PLVAR      = '01'
      ACT_BEGDA      = PCHBEGDA
      ACT_ENDDA      = PCHENDDA
      ACT_TDEPTH     = 2  
    TABLES
      RESULT_TAB     = ISWHACTOR
      RESULT_OBJEC   = IOBJEC
      RESULT_STRUC   = ISTRUC
    EXCEPTIONS
      NO_PLVAR_FOUND = 1
      NO_ENTRY_FOUND = 2
      OTHERS         = 3.
Note : The Variable ACT_TDEPTH denotes -->To indicate how many levels of an organizational structure should be processed in an inquiry/report, enter the appropriate level numberFor example, if the field contains a 3, the system processes three levels of the structure, beginning from the organizational unit you select as the root object, down.
The below fields always used default values unless for special cases.
HRRHAS-TFLAG - is checked if you need to fetch the texts
HRRHAS-VFLAG - is checked if you need to fetch the relation ship information
HRRHAS-AUTHY - is checked if you need to check the authorization
TEXT_BUFFER_FILL - denotes a test run
Remember the Objid is position based on the object type and relation you selected.
Thank you,
Kumar
