Allocation of one field value to another filed

Question

Hi
i'm having fileds as
CMC no
Area Code
Division
Demand
for example
CMC no = RD/FD
Area code =1
Division = 2
after entering this values
in DEMAND FIELD i had written Key next item trigger...in this trigger the code for concatenating values as
select AREA,
CONCAT('T',concat(:WATER_CON.WATER_AREA,CONCAT(:WATER_CON.WATER_DIVISION,WCMC)+1))
into :global.AREA,TEMPNO
from cmc_temp_no
where AREA=:WATER_CON.WATER_AREA;
after this i got a value as 'T1200001'
this value is allocated for the DEMAND field as like this
     :WATER_CON.DEMAND :=TEMPNO;
now after calculating this concatenated value i want to assign this value to the CMC no instead of assigning to the DEMAND Field
so please tell me what should i do

Answer 1

in the CMC NO field i have the trigger KEY-NEXT-ITEM
in that one i had written the code is
DECLARE
     W_COUNT NUMBER;
     W_COUNT1 NUMBER;
     ALERT VARCHAR2(50);
     CCNAME VARCHAR(75);
     CDNO VARCHAR(75);
     CPNO VARCHAR(75);
     CSNAME VARCHAR(75);
     CSCODE VARCHAR2(20);
     CLOC VARCHAR(75);
     CPIN NUMBER;          
     C NUMBER;
BEGIN
     IF :WATER_CON.WATER_CMC_NO='RD/FD' THEN     
GO_ITEM('WATER_CON.WATER_NAME');
     ELSE
          SELECT COUNT(*) INTO W_COUNT FROM APPS.RA_CUSTOMERS WHERE CUSTOMER_NUMBER=:WATER_CON.WATER_CMC_NO;
     if W_COUNT=0 then
               SET_ALERT_PROPERTY('DALERT',ALERT_MESSAGE_TEXT,' RECORD NOT FOUND');
     ALERT:=SHOW_ALERT('DALERT');
          GO_ITEM('WATER_CON.WATER_GROUP');
     ELSE          
               SELECT CUSTOMER_NAME INTO CCNAME FROM APPS.RA_CUSTOMERS WHERE CUSTOMER_NUMBER=:WATER_CON.WATER_CMC_NO;
               :WATER_CON.WATER_NAME:=CCNAME;
               :WATER_CON.WATER_AREA:=SUBSTR(:WATER_CON.WATER_CMC_NO,1,2);
               :WATER_CON.WATER_DIVISION:=SUBSTR(:WATER_CON.WATER_CMC_NO,3,3);     
     END IF;
          SELECT COUNT(*) INTO W_COUNT1 FROM XXCMW.CMW_BC_CUSTOMER_ADDR_HISTORY WHERE CUSTOMER_NUMBER=:WATER_CON.WATER_CMC_NO;
     if W_COUNT1=0 then
          MESSAGE('ADDRESS WAS NOT FOUND');
          :WATER_CON.WATER_NAME:='';
          :WATER_CON.WATER_DOOR_NO:='';
          :WATER_CON.WATER_PLOT_NO:='';
          :WATER_CON.WATER_STREET:='';
          :WATER_CON.WATER_STREET_CODE:='';
          :WATER_CON.WATER_LOCATION:='';
          :WATER_CON.WATER_PINCODE:='';
          GO_ITEM('WATER_CON.WATER_GROUP');
     ELSE
          SELECT NEW_DOOR_NUMBER,STREET_NAME,STREET_CODE,LOCATION,PIN_CODE INTO CDNO,CSNAME,CSCODE,CLOC,CPIN FROM XXCMW.CMW_BC_CUSTOMER_ADDR_HISTORY WHERE CUSTOMER_NUMBER=:WATER_CON.WATER_CMC_NO;
               :WATER_CON.WATER_DOOR_NO:=CDNO;
          --     :WATER_CON.WATER_PLOT_NO:=CPNO;
               :WATER_CON.WATER_STREET:=CSNAME;
                    :WATER_CON.WATER_STREET_CODE:=CSCODE;
               :WATER_CON.WATER_LOCATION:=CLOC;
               :WATER_CON.WATER_PINCODE:=CPIN;     
               :WATER_CON.WATER_AREA:=SUBSTR(:WATER_CON.WATER_CMC_NO,1,2);
               :WATER_CON.WATER_DIVISION:=SUBSTR(:WATER_CON.WATER_CMC_NO,3,3);     
                    GO_ITEM('WATER_CON.WATER_GROUP');
     END IF;
          :WATER_CON.WATER_AREA:=SUBSTR(:WATER_CON.WATER_CMC_NO,1,2);
          :WATER_CON.WATER_DIVISION:=SUBSTR(:WATER_CON.WATER_CMC_NO,3,3);
               :WATER_CON.WATER_AREA1:='';
     IF      :WATER_CON.WATER_AREA='10'THEN
     IF :WATER_CON.WATER_DIVISION>=142 AND :WATER_CON.WATER_DIVISION<=150 THEN
                    :WATER_CON.WATER_AREA1:='A';     
               ELSE IF :WATER_CON.WATER_DIVISION>=151 AND :WATER_CON.WATER_DIVISION<=156 THEN
     :WATER_CON.WATER_AREA1:='B';
     ELSE IF :WATER_CON.WATER_DIVISION>=923 AND :WATER_CON.WATER_DIVISION<=928 THEN
     :WATER_CON.WATER_AREA1:='A';
               END IF;
               END IF;
               END IF;
               END IF;
     END IF;
     END;
IN THE DEMAND field i have key nest item trigger
in this trigger i had generated TEMPno
not in the CMC no field
the code in the DEMAND field is
declare
     tempno varchar2(30);
begin
     IF :WATER_CON.WATER_CMC_NO='RD/FD' THEN     
     select AREA,CONCAT('T',concat(:WATER_CON.WATER_AREA,CONCAT(:WATER_CON.WATER_DIVISION,WCMC)+1)) into :global.AREA,TEMPNO from cmc_temp_no
     where AREA=:WATER_CON.WATER_AREA;
MESSAGE(TEMPNO);
     :WATER_CON.WATER_CMC_GROUP :=TEMPNO;
     end if;
     end;
     GO_ITEM('WATER_CON.WATER_flat_dem');
please tel me how can i assign this demand field to CMCno field after this trriger fired
Regards
