RSAU_READ_MASTER_DATA in transfer rules missing results or dump

Question

Hi Guys,
Anybody know about if the RSAU_READ_MASTER_DATA work in transfer rules??
I have a routine for field attribute derivation  from a infobject; putting the trans-structure as I_CHAVL and returning the E_ATTRVAL in result. But don't work and is hiring a dump of CALL_FUNCTION_CONFLICT_TYPE.
I tested with I_CHAVL equal to a string that is the key of a field in the infobject that I want to read; i haven´t the dump but don't work. The value is blank.
The code is the next:
CALL FUNCTION 'RSAU_READ_MASTER_DATA'
    EXPORTING
      I_IOBJNM   = 'KSTATSDSK'
      I_CHAVL    = TRAN_STRUCTURE-KSTATSDSK
  I_T_CHAVL                     =
  I_DATE                        =
  I_FLG_WHOLE_TABLE             =
      I_ATTRNM                    = 'KGRALSTA'
      IMPORTING
  E_STRUCTURE                   =
  E_TABLE                       =
      E_ATTRVAL                   = RESULT
EXCEPTIONS
      READ_ERROR                    = 1
      NO_SUCH_ATTRIBUTE             = 2
      WRONG_IMPORT_PARAMETERS       = 3
      CHAVL_NOT_FOUND               = 4
      OTHERS                        = 5.
Please, help me to see the error, if exist, or help me with other method for do this master data attribute read.
Thank you.

Hi Jeysi,
What's ur purpose here ??
If u're gonna read some data in master data, instead of using function, why don't u directly select to master data table ???
Usually the table name is /BIC/PX
X: Master data name.
/BIC/ => Customized one.
But if you want to get the information regarding what the table is, you can open directly respective master data info-object, and you go to master data tab.
In over there, you'll see the box whose label is Master data tab.
You can use SELECT command in ur corresponding transfer/update rules..
SELECT *
  FROM ..
  INTO CORRESPONDING FIELD OF TABLE ..
  WHERE ..
Hopefully it can help you a lot.
Regards,
Niel.
