Operation-ID digit limitation for Collaboration

Hi all

We're using yield confirmation collaboration regulative. Sometimes it works, sometimes it doesn't. If it Fails, it doesn't create the XML-file.

We get the error message "com.sap.me.Frame.Domain.RequiredValueValidationException: class com.sap.me.common.ObjectReferenceref (Meldung 16061) at complete of the Operation.

We use SAP ME 6.0.

Now we found out, that it might depend on the length of the Operation-ID. If it is longer than 18digits, it seems not to work.

Prior to adjust all the Routers and create new operations and routers, we would like to be more safe about this. Therefore my question:

Could you approve this as a possible error cause?

Thanks a lot.
