Hi, I wrote/copied a simple program that calls USR1058 that gets the DBID and FNR for a given table name. It works fine in our test environment but when I run it in system, I get the following error: -4125 The requested file description is not available. I’m wondering why and if there’s an alternative natural API I could call? Thanks! ---
