The RFC for IINTEGRATION_DIRECTORY_HMI is not working in our PI 7.1 environment. We are getting a "500 Internal Error" when we test this in SM59. We are also unable to get a successful refresh using SXI_CACHE. We have verified with Help.sap.com that the PIISUSER has the right roles and the user id and password are correct.
The details indicate we should check the webapplicationexception log. Where can this be found?
Any ideas as to what is causing our refresh to fail?
