If your install or upgrade has been unsuccessful, some objects may remain in the LANSA Work library. This library is created during the install and upgrade and is deleted by LANSA_CLN if the install was successfully completed. The Work Library's name is LANSAINSxx (where xx is a derived number.) Each install and upgrade process will create its own unique version of the work library.
You should delete this library if it remains after the install or upgrade.
