Error during RFC Look UP

[Former Member]

Hi,

When a try to display queue of a RFC lookup i am getting below error.

"Generic exception".

What could be the problem?

[Former Member]

Hi,

Check whether the Business Service and communication channel name which you specified in the lookup program created and activated in the intgeration directory.

[Former Member]

Yes. Business Service and communication channel are created and activated.

[Former Member]

Yes.Business Service and communication channel are created nd activated.

Hi,

Increase the trace level to 3 in SXMB_ADM for IE Configuration and then run your mapping in the test tab of the mapping.

You can get more details about the problem.

Post some more details of the error to get better answers.

it shows error in the target field

/PEXR2002/IDOC/HSBCEXTN//PEXR2002/IDOC/HSBCEXTN/*ErrorType; root message: Generic Exception

can you check how this gets populated

Also check for any error in RFC receiver channel in the monitor

[Former Member]

I have a RFC which fetches information from custom PI tables. There are some validation done in the RFC. If the validation fails, an exception is raised. Those errors caught here are mapped to Error Type which is a variable.

Which monitor are you talkng about? I have put error log from SXMB_MONI already. Are you talking about this?

[Former Member]

check RFC receiver in communication channel monitoring

BTW if no exception is raised in RFC does the mapping work successfully

[Former Member]

Yes.

[Former Member]

There is no problem with RFC reciever channel . I checked in monitoring.

Its saying message processed for interface.

[Former Member]

Hi,

How you are capturing the RFC return value when an exception is raised in RFC? Can you paste your look up code here so that it may throw more light on the problem.

Regards,

Vineetha.

[Former Member]

Hi Veenitha,

I cannot paste the entire code here but yes i can try and explain in my very best to u what exactly have we done.

In se80, we have function module where, in the exception tab we have defined few ecpetion objects with its key and value. For example key is "Creditor bank details" and value is "Missing Creditor Bank ID".

In the function module, validations are done and if an exceptin needs to be raised the line of code over there is " Raise Creditor bank details".

Now, in the maaping, where we are calling this RFC, while defining the inputs and outputs to this RFC we enable the Use exception checkbox which is available in there. Then what ever exception is raised in the RFC is caught through this output and is stored in a variable. This variable is ERROR TYPE in our mapping that you can see in the trace.

Hope this is clear.

[Former Member]

Hi Ravi,

Could you tell me how to enable trace 3 through SXMB_ADM.

If you can provide the steps for it, that would be better.

[Former Member]

Hi,

Check this blog /people/michal.krawczyk2/blog/2005/05/10/xi-i-cannot-see-some-of-my-messages-in-the-sxmbmoni to increase trace level

Prakash

[Former Member]

Hi Guys,

This is resolved now. I had to apply latest support package (SP07) on PI.

[Former Member]

Hi,

RFC lookup is done only at the run time. Hence you cant see its queue at design time.

Regards,

Shweta.
