User exit Debug

Hello Abapers

I am trying to write an user exit to extract data from knov table and append it in E1EDP05 segment in the Quotes.ORDERS05 idoc.

For this i am using EXIT_SAPLVEDE_002 and include ZXVDEU02.

My code is like this

DATA: WA_E1EDP05 LIKE E1EDP05.

Types: begin of t_konv,

*include fileds from konv.

KSCHL LIKE KONV-KSCHL,

BETRG LIKE KONV-KWERT,

KRATE LIKE KONV-KBETR,

UPRBS LIKE KONV-KPEIN,

MEAUN LIKE KONV-KMEIN,

KOEIN LIKE KONV-WAERS,

END OF T_KONV.

DATA: it_KONV TYPE STANDARD TABLE OF t_KONV INITIAL SIZE 0,

wa_KONV TYPE t_KONV.

IF INT_EDIDD-SEGNAM EQ 'E1EDP05'.

MOVE INT_EDIDD-SDATA TO WA_E1EDP05.

WA_E1EDP05-ALCKZ = '+'.

SELECT kschl kwert kbetr kpein kmein waers FROM konv INTO CORRESPONDING FIELDS OF TABLE it_KONV WHERE KNUMV EQ XVBAK-KNUMV

and kposn eq XVBAp-posnr and KSCHL eq 'VPRS'.

loop at it_KONV into WA_KONV .

WA_E1EDP05-KSCHL = WA_KONV-KSCHL.

WA_E1EDP05-BETRG = WA_konv-betrg.

WA_E1EDP05-KRATE = WA_konv-KRATE.

WA_E1EDP05-UPRBS = WA_konv-UPRBS.

WA_E1EDP05-MEAUN = WA_konv-MEAUN.

WA_E1EDP05-KOEIN = WA_konv-KOEIN.

MOVE WA_E1EDP05 TO INT_EDIDD-SDATA.

append INT_EDIDD.

endloop.

ENDIF.

It doesn't error but it doesn't give the result i want . I can see many E1EDP05 segments in the idoc with no useful data , all 0s . Is there something wrong with my code . Any help is appriciated.

Regards
