Error in Customer Exit for Remodeling Rule

Hi,

I have created a remodeling rule in order to add a new key figure ZPRECVAL using a customer exit class ZCL_RSCNV_EXIT_ZPRECVAL.

This class is copy of template CL_RSCNV_USER_EXIT_SAMPLE and I have modified the code by my logic: get the calday and access to

other DSO using this calday in order to retrieve the ZPRECVAL.

the code of my class is activated and doesn't show error, but when I check the Remodeling Rule the following error is showed:

"Error in Customer exit" message RSCNV814. Then I can not execute the remodeling rule.

I have been checked the code and the error is in the function RRSI_SID_VAL_SINGLE_CONVERT because if I comment these lines the

remodeling rule does not show error. My code is:

_________________________________________________________________________

METHOD if_rscnv_exit~exit.

FIELD-SYMBOLS: <l_s_old> TYPE any,
<l_fillfield> TYPE any,
<l_newfield> TYPE any.
DATA: l_chavl TYPE rschavl.

*****************************************************
* Assign the references to field symbols
*****************************************************

ASSIGN c_r_newfield->* TO <l_newfield>.
ASSIGN i_r_old->* TO <l_s_old>.

*****************************************************
* To use the individual fields of the old table
* structure (e.g. SID_0CALDAY), assign these fields
* to field symbols using the field name.
*****************************************************

ASSIGN COMPONENT 'SID_0CALDAY' OF STRUCTURE <l_s_old> TO <l_fillfield>.

CALL FUNCTION 'RRSI_SID_VAL_SINGLE_CONVERT'
EXPORTING
i_iobjnm = '0CALDAY'
* I_S_COB_PRO =
i_sid = <l_fillfield>
* IMPORTING
* E_CHAVL =

* E_S_NODESID_ASO =
* EXCEPTIONS
* NO_VALUE_FOR_SID = 1
* X_MESSAGE = 2
* OTHERS = 3
.
IF sy-subrc <> 0.
* Implement suitable error handling here
ENDIF.

Note: the rest of the code is not neccesary because the error is in these lines.

I don't know the problem. The infocube is filled, the infoobject 0CALDAY is included in the cube and the class code is active.

I have created other remodeling rules and I had not this problem. Please, could you help me?

Thanks in advance,

regards,
