Hi Mani,
Follow the following steps :
1. Create RFC destination for both the systems on CRM and R/3 in SM59.
2. Create the logical systems and assign clients to logical system in SALE transaction both on CRM and R/3.
3. Create a user in the R/3 table CRMCONSUM with the name CRM.
4. Maintain the Middlware Parameter tables on CRM : Table SMOFPARSFA:
   Create an entry for following parameter entry:
   Key - R3A_COMMON
   Para name - CRM_DEFAULT_DESTINATION
   Value - R/3 logical system
5. Maintain the parameter tables on R/3 system : CRMRFCPAR, CRMPAROLTP
    CRMRFCPAR :
    Create new entry with following data:
    User - CRM
    Object name - *
    RFC Destination - RFC destination for CRM
    Load types - All Load Types
    In Queue flag - X
    Send XML – No XML
    CRMPAROLTP :
    Create the following parameter entry:
    Para name - CRM_DEFAULT_DESTINATION
    User - CRM
    Value -  Name of the CRM logical system
6. Create Sites and attach subscriptions in Admin Console : Tcode SMOEAC
    Create a Site as CRM and another as R/3. Attach the required subscriptions to the R/3 site.
7. Register the queues in SMQR and SMQS transactions.
