Selective Deletion of Infocube data

Question

BW experts,
I have a scenario where in "rough" data already stored in an InfoCube will be replaced by a more "intelligent" data from another source. The deletion/replacement of data should happen without manual intervention (cause flat file data files arrive at a schedule time and should be loaded "automatically"into the cube) What are my options here? I currently know that it is possible to delete infocube contents using function module 'RSDRD_SEL_DELETION' (perhaps do it in the Update Rule).
1) Is there another way (more "SAP Standard" or more "intelligent")?  I need to delete based on characteristics  that can be found in the file (e.g. the file has data for 0MATERIAL, 0CALWEEK).
2) What are the "watch outs" for using function module 'RSDRD_SEL_DELETION'?
Please advise.
Thank you very much.

Hello Emmanuel,
   In ABAP programe Just used the Infocube Name and the selection condition on what basis you want to delete.
See Below the code.
*add the fiscper selection in L_THX_SEL table for seletion of data
CLEAR L_SX_SEL.
  L_SX_SEL-IOBJNM = '0FISCPER'.
    CLEAR L_S_RANGE.
    L_S_RANGE-SIGN = 'I'.
    L_S_RANGE-OPTION = 'EQ'.
    L_S_RANGE-LOW = TFISCPER.  "yr data.
*--this is imortant otherwise data wil not delete
    L_S_RANGE-KEYFL = RS_C_TRUE.
    APPEND L_S_RANGE TO L_SX_SEL-T_RANGE.
  INSERT L_SX_SEL INTO TABLE L_THX_SEL.
**get the selection for company
  CLEAR L_SX_SEL.
  L_SX_SEL-IOBJNM = '0COMPANY'.
    CLEAR L_S_RANGE.
    L_S_RANGE-SIGN = 'I'.
    L_S_RANGE-OPTION = 'EQ'.
    L_S_RANGE-LOW = VARIANT.
*--this is imortant otherwise data wil not delete
    L_S_RANGE-KEYFL = RS_C_TRUE.
    APPEND L_S_RANGE TO L_SX_SEL-T_RANGE.
  INSERT L_SX_SEL INTO TABLE L_THX_SEL.
*function module for selective deletion..
CALL FUNCTION 'RSDRD_SEL_DELETION'
  EXPORTING
    I_DATATARGET              = 'IFIBIV'
    I_THX_SEL                 =  L_THX_SEL
  I_DEL_ACTIV               = RS_C_TRUE
  I_DEL_UPDATE              = RS_C_FALSE
  I_DEL_CHANGE              = RS_C_FALSE
  I_AUTHORITY_CHECK         = RS_C_TRUE
  I_MODE                    = RSDRD_C_MODE-CHOOSE
  I_THRESHOLD               = '0.1'
  I_PARALLEL_DEGREE         = 1
  I_NO_LOGGING              = RS_C_FALSE
  I_NO_COMMIT               = RS_C_FALSE
  I_NO_ENQUEUE              = RS_C_FALSE
  I_SHOW_REPORT             = RS_C_FALSE
  I_TRANSACTIONAL_ODS       = RS_C_FALSE
  CHANGING
    C_T_MSG                   =  L_T_MSG
EXCEPTIONS
  X_MESSAGE                 = 1
  INHERITED_ERROR           = 2
  INVALID_TYPE              = 3
  OTHERS                    = 4
IF SY-SUBRC <> 0.
MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
        WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.
Hope This will help.
In Start Routine there is no disadvantage to delete the data from data package.
But it depened on the scenario and requirement.
