Old PLA format from Plato does not allow access to FlexRip tickets in Automation Engine.
Symptoms
When selecting a PLA file format in Automation Engine Pilot, you do not have access to FlexRip tickets for any output flavour. But when selecting a PDFPLA file, the FlexRip tickets are available.
Solution
PLA layout format is part of the old GRS document format group and is no longer a supported input type for FlexRip.
In Plato, open the old PLA document.
Click File > Export Layout. Here you may set parameters for exporting the PLA format to PDFPLA.
Save the file.
You may now open the PDFPLA and work in Plato as needed.
