SAP XI/PI excel to custom RFC

[AJeB]

Hi Everyone,

in my old custom RFC there are 3 import parameters ( IV_NAME, IV_AGE, IV_ADDRESS )

Existing

Field	IV_NAME	IV_Age	IV_Address
Value	NAME1	18	Canada

need to add

Field	IV_CITY
Value	CITY1

in the XI/PO mapping the parameter is ( IV_NAME, IV_AGE, IV_ADDRESS )

In the new requirement we need to add and get the City from file created from XI/PO, I already adjusted the custom RFC and added the IV_CITY and the XI/PO team also added the new parameter IV_CITY to the mapping. while doing debugging, I checked the import parameter in the RFC and saw that the RFC did not receive the City value, what could be the cause of the issue?

Hi,

it's a problem that i know very well. The signature of the XML-RFC is somewhere cached and i haven't yet found a way to invalid the cache. You have to rename the communication channel that is used - than it's works again. Just a new activation of the CC isn't enough to reload the signature. 

I guess you are consuming an RFC lookup from a mapping, correct? I my case it was a SOAP lookup and giving the channel a new name solved the issue.

That's also my idea: XI/PO caches the function module signature (importing/exporting parameters). If the FM has been changed, but XI/PO not yet updated, then the new parameters are not yet known on XI/PO side, and the RFC protocol in such a case is designed to just ignore unknown data.

I know that for example in the SAP Business Connector (which is similar to XI/PO) there is a button "Clear DDIC Cache", which can be used precisely in those cases. The FM signature is deleted from the cache and then looked up again from the backend DDIC, when it's needed the next time.

I would assume that XI/PO has a similar "Clear Cache" feature. If not, you will have to restart the XI/PO system...

We already tried to refresh the channel but still not working

I didn't say anything about a "channel". (In fact, I don't even know what a "channel" is...)

The JCo cache is JavaVM-wide, so if XI/PO does not have a button that says "Clear Cache", then you will need a restart of the Java VM (which means restart of the XI/PO system).

the basis team refreshed the JCo Monitoring Metadata Cache of RFC and its working as expected. thanks for the ideas
