Answer 1

This normally means that you are trying to insert data on a screen for which a particular field is not available.
So check screen number, screen fields and report name. In case of screen fields, use F1, F9 (technical information), and check the name of the screen field for batch processing (all the way at th bottom of the pop-up). This can differ from actual name of the screen field.
If all this is ok, try to create a recording of the transaction with SM37.
