Reset flag

Question

Hi Experts I need an advice for the below case.
A flag which is set in the EBAN must be reseted. This
is the programm. It doesn't do that. What can be reason for that.
This is the Function Module Call from SAP SRM System with destination command.
CALL FUNCTION 'ZBM_RESET_FLAG'
DESTINATION 'RV3CLNT888'
  EXPORTING
    BANFNUMBER        = ls_ITEM-EXT_DEMID
EXCEPTIONS
   NOT_RESETED       = 1
   OTHERS            = 2.
The Function Module is in the the backendsystem (R/3).
FUNCTION ZBM_RESET_FLAG.
*"*"Lokale Schnittstelle:
*"  IMPORTING
*"     VALUE(BANFNUMBER) TYPE  BANFN
*"  EXCEPTIONS
*"      NOT_RESETED
  data lt_eban type table of eban.
  data ls_eban type eban.
  data:  l_r_banfn type table of ZBANFEN.
SELECT * FROM eban into table lt_eban where BANFN EQ BANFNUMBER AND LOCKFLAG EQ 'X'.
  IF SY-SUBRC IS INITIAL.
    LOOP AT lt_eban INTO ls_eban .
      clear: ls_eban-LOCKFLAG .
      modify eban from ls_eban.
    ENDLOOP.
    ELSE.
    raise NOT_RESETED.
  ENDIF.
ENDFUNCTION.

Dear Colleques,
the problem is still existing.
I have inserted a infinite loop and have called t-code sm50 and debugged this coding.
There is no sy-subrc <> 0 and any error message.
Is it not possible to update a dictionary table via remote call like in my case ?
What is worng here ?

data lzahl1 type i .
data lzahl2 type i .
lzahl1 = 0.
lzahl2 = 2.
while lzahl1 < lzahl2.
clear sy-subrc.
endwhile.
  data lt_eban type table of eban.
  data ls_eban type eban.
  data:  l_r_banfn type table of ZBANFEN.
  CALL FUNCTION 'CONVERSION_EXIT_ALPHA_INPUT'
    EXPORTING
      INPUT  = BANFNUMBER
    IMPORTING
      OUTPUT = BANFNUMBER.
  SELECT * FROM eban into table lt_eban where BANFN EQ BANFNUMBER AND LOCKFLAG EQ 'X'.
  IF SY-SUBRC IS INITIAL.
    LOOP AT lt_eban INTO ls_eban .
      UPDATe eban set lockflag = ' ' where banfn = ls_eban-BANFN.
     commit work and wait.
    ENDLOOP.
  ELSE.
    raise NOT_RESETED.
  ENDIF.
