Thanks John for replying. We don't use ProcessFlow but I have ensured that the PSA AppSet setup for ProcessFlow is correct -- according to the documentation in Lawson Services Automation Installation Guide for integrating with LSF9.
When running the ssoconfig utility (ssoconfig -c, Manage Lawson Services, Load service and Identity file), I receive the following in the ssoconfig.xml.err file.
