SAP NetWeaver Business Client ,Portal connection, getNavigationTree method

[Former Member]

Hy, i have this problem: i set a connection to Portal on SAP NetWeaver Business Client and after that i insert my user and password on logon portal screen, i receive this message: internal server error (500) - Exception in method getNavigationTree.

I find that getNavigationTree is a method of web service WSNavigation and i tested it on the portal and i didn't have no error exception.

Could you help me?

Thank's in advance.

we have the same problem. Has anybody solved it yet?

[Former Member]

Hy Andreas, to use portal connection , the stack java must be upgrated to SPS14.

[Former Member]

Hi Andrea,

we are already fresh on SPS14.

So there must be another reason for this error.

We are getting an answer from the server...., but the answer contains

.....<faultcode>SOAP-ENV:Client</faultcode><faultstring>Exception in method getNavigationTree.</faultstring>....

Do you have any other idea?

Best regard

Could you explain all exception text, please?

Thank's

Hi,

I assume the problem is the parameter numberOfLevels, which is on "-1".

We are getting the same problem when testing it manually.

Thanks

Andreas

Control on the BW system if service "SOAP" is active.

Trans: SICF,

service : default host-sap-bc-soap

I hope to help you.

the system is an EP core system with java stack only...so there is no SICF transaction.

Hi,

we tested the WS in test mode with the following combinations:

numberOfLevels = -1

lastModification not initial

-> Successful, but empty result

numberOfLevels = -1

lastModification initial

-> Error 500

numberOfLevels = 1

lastModification initial

-> Successful, first hierarchy is being set

numberOfLevels = 2

lastModification initial

-> Error 500

So we are trying the SPS 15 from last week, maybe it helps.

Thanks

Hi All,

I see this message was created in 2008 and we are testing now and still getting the same error.

We are on NWBC 3.0. Has anybody found a solution for this problem?

The complication is we are taking a bunch of Portal roles and grouping them together and assigning that group to a userid.

That is when we get the same error as described in this thread. We have provided merge IDs for different iViews and I suspect if there are too many iViews with the same merge ID, NWBC does not like it.

We have created a super role containing about 7-8 folders in detailed navigation with a total of about 1000+ transactions and it seems to work fine. So i think NWBC can handle the volume but the Merge IDs is where it is getting tripped.

Would appreciate if somebody can help us.

regards,

Atul
