I can’t seem to locate it. It’s not in the list of any tcl procs on any site. I can only see it when I go to add. Is there a folder of standard tclprocs that are included?
Sounds like your predecessor may have put this in the root. create_ack doesn’t sound like a standard thing that we shipped with Cloverleaf.
In 6.1, look under $HCIROOT/tclprocs. The tclIndex file will tell you what file the proc resides in.
Moving forward, suggest you create a master site and put it in there. This is the best way to carry forward changes, as changes to the root are not automatically migrated when you upgrade.
