The screen allows for an empty line to allow for the screen to permit the table to be empty (ie, when using an invalid QB range). A workaround is to re-run the quickbar range.
Our development team have enhanced this functionality in FactoryMaster version 20.10.14
Please upgrade to this version (or version 20.11.09).
Scroll past last row in manufacturing route maintenance and all the buttons are greyed out
When I go into manufacturing route and go beyond the last record in the table the 'Copy' button becomes disabled and remains so when you go back up to a part in the table. You cannot use this button again unless you exit the screen and go back in.
