Serious Performance Problems in ABAP Reports

Question

Hi All,
We are developing ABAP reports for SAP IS-U/CCS Modules and facing Performance issues.Whole scenario is given below.Please suggest some solution.
1. Total No. Of Business Partners = 1500000
2. Reports Selection Criteria are of two types:
     a) GSBER(Business Area) - Selection for atleast 200000 Business Partners
     b) Cokey(Division)     - Selection for around 1000 to 50000 Business Partners
3. For implementing our reports logic we have to access several tables all of which are very large.They are :
     Table Name     No. of records (Appx)          
     DBERCHV               20000000
     DBERCHZ1              20000000
     DBERDLB               20000000
     DFKKKO                20000000
     DFKKOP                20000000
     EANLH                  4000000
     ERCH                  10000000
     ERCHC                 10000000
     ETTIFN                30000000
     EVER                   1500000
     FKKVKP                 1500000
     TECOKT                     500     
     TGSBT                       12
4. Due to large no. of records we are facing problems at two levels:
     a) OpenSQL Statement is taking too much time for data selection
     b) Since large no. of records are selected Corresponding loops and data processing also takes much time
5. We have tried almost all ABAP Performance optimization techniques such as using Index, SQL optimization techniques,Read Table Optimization, Loop Statement Optimization etc. but there is not much improvement.
6. For example one of our Reports "R15" takes around 1500 seconds for 1000 Business Partners.
Its Code is attached below:
