Hi,

When you create a system, it adds entry at many places like business system, ports and stuff like that. If you get this message that the system is already existing that means that it was created successfully last time. Just try to create a JCO connnection and see you might be able to see your message server populated.

Dear Murtuja

Yes u r right but in that entries all are available but message server and logon Group entry are not there....if i try to enter that only value (message server name or Group name) it is throwing error...

my all RFC's are in RED. When i creating that RFC, there is no entry in message server..so i am unable to create JCo.

so i decided to delete that Technical system and refresh and recreate it... still while recreation it is giving already system is defined..

any suggestions please..

Thanks in advance

in system landscape directory, search for the ABAP WAS host system and if found, delete the system.

2. <SID> of ABAP

Installation number

Database Host <host name>

3. Message Server Host: <host name>

Port: 3600 + <nr>

3.1 Log on group would've shown, else

3.1.1 Go to SMLG in ABAP System, choose, Log on group with ext-RFC enabled.

Centrail Application Server:

Host Name: <host name>

inst. number <nr>

4. Application server

4.1 Add application server

host name< host name>

inst. num< nr>

5. Add Clients
