Conversion Routine... plz help

Question

Dear Gurus,
There is a text field in R3 called as SGTXT related to some finance table... some of the records in this field directly start with '#' character and then the details.. Well here is the problem.. I m loading to ODS 0FIAR_O04 and it ends up in error due to the above mentioned problem.. the infoobject which carry the data from SGTXT field is 0POSTXT...
I decided to go for a conversion routive in transfer rule for this field.. but i dont know how to write routines.. can you plz help me with the steps as well as the code to remove '#' from SGTXT.... Thanks.
For more help i m attaching the conversion routine with is automatically generated by system... only i hv to add code to remove '#' character... kindly go thru it and suggest me where to add and what to add...
here it is
PROGRAM CONVERSION_ROUTINE.
Type pools used by conversion program
TYPE-POOLS: RS, RSARC, RSARR, SBIWA, RSSM.
Declaration of transfer structure (selected fields only)
TYPES: BEGIN OF TRANSFER_STRUCTURE ,
InfoObject 0POSTXT: CHAR - 000050
SGTXT(000050) TYPE C,
END OF TRANSFER_STRUCTURE .
Global code used by conversion rules
$$ begin of global - insert your declaration only below this line -
TABLES: ...
DATA: ...
$$ end of global - insert your declaration only before this line -
FORM COMPUTE_POSTXT
Compute value of InfoObject 0POSTXT
in communication structure /BIC/CS0FI_AR_4
Technical properties:
field name = POSTXT
data element = /BI0/OIPOSTXT
data type = CHAR
length = 000060
decimals = 000000
ABAP type = C
ABAP length = 000120
reference field =
Parameters:
--> RECORD_NO Record number
--> TRAN_STRUCTURE Transfer structure
<-- RESULT Return value of InfoObject
<-> G_T_ERRORLOG Error log
<-- RETURNCODE Return code (to skip one record)
<-- ABORT Abort code (to skip whole data package)
FORM COMPUTE_POSTXT
USING RECORD_NO LIKE SY-TABIX
TRAN_STRUCTURE TYPE TRANSFER_STRUCTURE
G_S_MINFO TYPE RSSM_S_MINFO
CHANGING RESULT TYPE /BI0/OIPOSTXT
G_T_ERRORLOG TYPE rssm_t_errorlog_int
RETURNCODE LIKE SY-SUBRC
ABORT LIKE SY-SUBRC. "set ABORT 0 to cancel datapackage
$$ begin of routine - insert your code only below this line -
DATA: l_s_errorlog TYPE rssm_s_errorlog_int.
RESULT = .
returncode 0 means skip this record

ABORT = 0.
$$ end of routine - insert your code only before this line -
ENDFORM.
FORM INVERT_POSTXT
Inversion of selection criteria for InfoObject 0POSTXT
This subroutine needs to be implemented only for SAP RemoteCubes
(for better performance) and for the Report/Report Interface
(drill through).
--> I_RT_CHAVL_CS Ranges table for current InfoObject
--> I_THX_SELECTION_CS Selection criteria for all other InfoObjects
<-- C_T_SELECTION Selection criteria for fields of
transfer structure
<-- E_EXACT Flag: Inversion was exact
FORM INVERT_POSTXT
USING I_RT_CHAVL_CS TYPE RSARC_RT_CHAVL
I_THX_SELECTION_CS TYPE RSARC_THX_SELCS
CHANGING C_T_SELECTION TYPE SBIWA_T_SELECT
E_EXACT TYPE RS_BOOL.
$$ begin of inverse routine - insert your code only below this line-
DATA:
L_S_SELECTION LIKE LINE OF C_T_SELECTION.
An empty selection means all values
CLEAR C_T_SELECTION.

Selection of all values may be not exact
