Calling Remote enabled Function module in java using RFC Destination

[former_member236708]

Hi

We are on Portal 7.3 ehp1 sp9.

Steps followed are :

RFC Destination called “SAP_RFC” has been created as below :

Configuration -> Destinations -> RFC Destinations

Connection and Transport:

-------------------------------------

Load balancing :Yes

Provided : SystemID / MS Server / MS Server Service / Logon Group / Gateway Host / Gateway Service

SNC : Inactive

Logon Data:

------------------

Authentication : Current User (Assertion Ticket)

Language : EN

Client : XXX

Repository Connection:

-----------------------------------

Destination Name : This Destination

Specific Data:

----------------------

pooled Connection Mode : Yes

Max : 5

Size : 10

Max. wait time : 10,000

Ping Destination results : Successfully connected to System XXX as per user XXXXXXX.

JAVA Code as Follows:

JCoDestination destination = JCoDestinationManager.getDestination("SAP_RFC");

//destination.ping();

JCoRepository repository = destination.getRepository();

JCoFunction function = repository.getFunction("FM_NAME");

function.execute(destination);

Lines highlighted in RED color throwing an error as below :

{"ERROR":"Initialization of destination JCO_RFC failed: Incomplete logon data. on <SID> mshost <MS_HOST>/ com.sap.conn.jco.JCoException: (103) JCO_ERROR_LOGON_FAILURE: Incomplete logon data. on SID mshost MS_HOST"}

And found that no COOKIE with the name “SAP_SESSIONID_<system>_<client>” was not found, I am afraid that “Assertion Ticket” was not created in above scenario.

To confirm SSO configuration working, i have followed below steps:

1) Created System Object pointing to R/3 and tests were successful for authentication type "SSOLOGONTICKET / ASSERTIONTICKET"

It's J2EE application, no references or any other additional configuration been made part from above.

Any help ?

Thanks

Hi Mohan,

Hope you are doing good.
The error shows that the parameters are missing. can you check the parameters with the backend details. If teh issue persists, enable the JCo trace (to level 5) as per note 628962. Check:

<https://wiki.sdn.sap.com/wiki/display/SI/Java+Connectivity>

(check JCo trace activation via Java system properties)

Thank you and have a nice day :).

Thanks for your reply.

Ping Destination results : Successfully connected to System XXX as per user XXXXXXX.

If anything missing / wrong, test would fail right ?

Before i proceed further, i would like to know whether the approach is correct or not ?

You can see above, an error message from trace file.

Error message from jco_rfc file : RfcGetException rc (7) message: Incomplete logon data.

Message from log viewer under NWA : Assertion ticket could not be retrieved. Error was null

Thanks

Hi Mohan,

I remember such an issue with a previous customer. There is a known issue with the assertion tickets. Please see note 1754939  No logged in user exception. Also, due to the intertwined dependencies, it is highly recommended  to deploy the latest patches for the other SCAs as well mentioned in note 1794179 when you do a SCA upgrade. Deploy using any tool mentioned in sap note 1715441.

Hi

Error: Assertion ticket could not be retrieved, Error was null.

Info : Returned Destincation JCO_RFC, type RFC to user <Unknown User>.

Thanks

[hemanth2]

Great, is the issue resolved then and was the issue with the s_rfc authorizations?

[former_member236708]

Hi

Nope, not yet resolved.

It could not be authorization issue, because changing RFC Destination from "Assertion Ticket" to "Logon Method" works fine and FMs being called successfully.

Problem is when we set "Assertion Ticket"

Still finding for solution.

Thanks for helping ..

Hi,

Then please apply the note 1754939 as i mentioned earlier. there is a bug that was found sometime back and should help in this case.

Hi

Here is reply from our basis team, saying that note 1754939 is not applicable.

The component versions in the note does not apply to our system (ours is 731, not 711). Furthermore, we are already at the latest patches for SP9 (patches are current as of 14.04.2014).

Thanks
