How to debugge RUN_CURR_CONVERSION

Hi experts!

I want to debug the script logic fxtrans.lgf but i dont want to use the UJKT.

I want to use SE24 transacion. I try debug the Method RUN_CURR_CONVERSION on the class CL_UJP_CURR_CONVERSION

but when I try to execute the method The following DUMP occurs:

GETWA_NOT_ASSIGNED

I use the following parameters:

I_APPSET ZTECSA

I_APPLICATION LEGAL

I_CATEGORY 100

I_CURRENCY BRL

I_GROUP G_T1

I_MODULE_ID ???????

I_RATEENTITY 1001

I_REF_TIMEID 2010.DEC

I_SIMU_CAT_MEMBER ?????

I don´t know how information i need to use on fields ????

My script logic:

*RUN_PROGRAM CURR_CONVERSION

//*SELECT(%GROUPS_SET%,"[ID]",GROUPS,"[CURRENCY_TYPE]='R'")

CATEGORY = %VERSAO_SET%

GROUP = %GROUPS_SET%

TID_RA = %MESANO_SET%

RATEENTITY = GLOBAL

OTHER = //INTCO=%INTCO_SET%]

*ENDRUN_PROGRAM

Thanks
