Need to get NULL values!

Question

Hi,
I have a query like following...
SELECT CA.C_PROJECT_ID, SUM(CA.AMTACCTCR - CA.AMTACCTDR) AS AMOUNT
FROM CUS_ACCTDIM_FACT_ACCT CA
LEFT JOIN M_PRODUCT MP ON MP.M_PRODUCT_ID = CA.M_PRODUCT_ID
WHERE MP.PRODUCTTYPE = 'S'
GROUP BY CA.C_PROJECT_ID;
Result is:
PROJECT AMOUNT
1000087     4175
1000093     4000
But I need to get the following result:
PROJECT AMOUNT
1000087     4175
1000088     
1000089     
1000090     
1000091     
1000092     
1000093     4000
I mean I need to get all the project ids but amount should show only to the records that match the condition. Other projects will have null value.
Can someone help me how to write query to get this output?
Thanks in advance.

Kalyogi,
Based on your information, I created following tables and added but if you can post your tables and some sample data for both then it will be easy to help you in better way.
But check this test case as it gets desired output you are requesting for, you can run this entire test in your setup and verify
CREATE TABLE cus_acctdim_fact_acct (
   c_project_id NUMBER,
   amtacctcr NUMBER,
   amtacctdr NUMBER,
   m_product_id NUMBER
SET DEFINE OFF;
Insert into TESTME.CUS_ACCTDIM_FACT_ACCT
   (C_PROJECT_ID, AMTACCTCR, AMTACCTDR, M_PRODUCT_ID)
Values
   (1000087, 4190, 15, 1111);
Insert into TESTME.CUS_ACCTDIM_FACT_ACCT
   (C_PROJECT_ID, AMTACCTCR, AMTACCTDR, M_PRODUCT_ID)
Values
   (1000093, 4050, 50, 2222);
Insert into TESTME.CUS_ACCTDIM_FACT_ACCT
   (C_PROJECT_ID, M_PRODUCT_ID)
Values
   (1000088, 3333);
Insert into TESTME.CUS_ACCTDIM_FACT_ACCT
   (C_PROJECT_ID, M_PRODUCT_ID)
Values
   (1000089, 4444);
COMMIT;
CREATE TABLE m_product (
   m_product_id NUMBER,
   producttype VARCHAR2 (1)
   SET DEFINE OFF;
Insert into TESTME.M_PRODUCT
   (M_PRODUCT_ID, PRODUCTTYPE)
Values
   (4444, 'S');
Insert into TESTME.M_PRODUCT
   (M_PRODUCT_ID, PRODUCTTYPE)
Values
   (3333, 'S');
Insert into TESTME.M_PRODUCT
   (M_PRODUCT_ID, PRODUCTTYPE)
Values
   (2222, 'S');
Insert into TESTME.M_PRODUCT
   (M_PRODUCT_ID, PRODUCTTYPE)
Values
   (1111, 'S');
COMMIT;
SELECT ca.c_project_id, SUM (ca.amtacctcr - ca.amtacctdr) AS amount
FROM    cus_acctdim_fact_acct ca
     LEFT JOIN
        m_product mp
     ON mp.m_product_id = ca.m_product_id
WHERE mp.producttype = 'S'
GROUP BY ca.c_project_id;Regards
