Hi Anton,

Check

AI_DIRECTORY_JCOSERVER

SAPSLDAPI

LCRSAPRFC

If they are ok, do a full data cache refresh. Also check on this thread..

cheers,

Hi Prashanth,

every Connection is OK.

The rfc is correct. i have develop another rfc, very simple and i test this rfc. at first time it work's correct. if i changed the interface, i renamed the name or i changed the structure, the XI know's allways the old the name, the old structure.

cheers anton

Hi,

Did you try restarting the RFC Adapter service in Visual Admin? If not please try that

Hi Anton,

it seems I have the same problems. Have you found a solution.

Hi Matthias,

it seems the definition of the interface was incorrect. Here the developer has defined much fields with type STRING, than type CHAR512. Since he has define the fieldes in the correct type an length we haven no problems.

Hi Prashanth,

i have restart the RFC-Adapter, and the Logon Data for the Repository is correct.

If i show in the SXI_CACHE i think the cache had a problem with the refresh. i think the old data is always in the cache and it does not refresh

Hi Anton,

Could you test your AI_RUNTIME_JCOSERVER connection in sm59?

Go into SM59--> TCP/IP connections --> AI_RUNTIME_JCOSERVER, and test the connection.

i do it in the XI and the connection is OK

[Former Member]

Dear Anton,

When sending data to XI you should declare empty RFC with Structure you want to send in Export, then you should fill the structure and call the function with "destination" to XI.

[Former Member]

Dear Dmitry,

i do that so, but the XI send the message "can not generate template". If i changed the RFC, the XI get the old structure. What is the reason?

hi,

Please reimport RFC in integration repository, afterwards activate, deactivate and one more time activate your communication channel in integration directory. RFC metadata are cached.

Wojciech

Hi,

Did you reimport the RFC again into the IR? if not please do that and also check the mapping if that is perfect. Also try clearing the cache SXI_CACHE / CPA cache. If you still face the problem restart the RFC Adapter service in the visual admin.

i reimport the rfc more times and that has no effect. i call another rfc on the communication canal and i have the same effect. Can not generate template. i reduce the name of the rfc-name since it is 10 characters long and than it is ok for 1 times. after the first call he has the import parameter in the cache and this import parameter is allways the same. at first time i have get the structure t001, this is ok, than i get the structure t001w and he has allways the structure t001 in his description.

hi,

please to restart your communication channel. It should help.

a) deactivate channel, activate change

b) activate channel, activate change

The same effect you should achieve refreshing CPACache

I have deactivate the interface and the RFC-channel. if i send the rfc from the backend to the xi, i get the message "program MSI_ARGOS not registered". then i activate the interface and the RFC-channel. then i get the message again "server repository could not create the function template". if i refresh the cash with the transaction SXI_CACHE i have no effect.

Hi,

Please check what you can see in your adapter monitor(Runtime Workbench->component monitoring->Adapter Engine->Adapter monitoring).? Now it looks like your RFC adapet cannot read metadata, so please verify your logon.

I have changed the Logon Parameters to the repository, but this has no effect. the name and the password is right. i have checked this many times

[Former Member]

hi,

What can you see in adapter monitor?

Maybe user which you are using to read metadata is not authorized to do it?

Regards,

Wojciech

[Former Member]

In the adapter monitoring the rfc adapter writes no logs. but in the kommunicationschanel-monitoring the RFC is green and the logon is correct. i get the errors from the call from the backend.

here " Error: 2006-11-15 17:00:19 CET: com.sap.mw.jco.JCO$Exception: (123) JCO_ERROR_FUNCTION_NOT_FOUND: Server repository could not create function templat for 'Y_EGV_DSC_MSC_ORDER_ARGOS' caused by: java.lang.ArrayIndexOutOfBoundsException: - 128"

the user who read the metadata am i. i have sapall, sapnew.
