FAQ / + When upgrading from SYSPRO 6.1 SP1 and encounters “no characters” in the Source IT License “System:” field and a message “License Code is Invalid” is displayed when trying to license when relicensing directly from SYSPRO menu

On attempt to relicense BTS, SYSPRO will advise that an upgrade is required, proceed with the upgrade as the process has picked up that the latest version of files for BTS is required and this takes place by a ‘self-healing’ upgrade process where the old files are replaced with newer files as required and the triggers for BTS is also created correctly.


1. Always ensure that the latest BTS product has been installed
2. Do not run the “SIT001” program directly but rather run the BTS re-license program “BTPLIC”
