Here is how I would do this job. Export the 432 page .indd as a pdf and then do an Extract Pages from within Acrobat (extract pages as separate files) to make 432 individual pages named Ticket 1, Ticket 2, Ticket 3...etc.
Then make an Excel file with 11425 rows and 3 columns...
Ticket,BackVersion,Number
1,Back1,00001
1,Back1,00002
1,Back1,00003
...
1,Back1,00065
2,Back2,00066
...
2,Back2,00130
...
432,Back3,11425
and so forth and save as a .csv. If you know Excel and how to fill cells efficiently, this shouldn't take too long. (It will take some time but iIt should be faster than trying to work with 432 different FusionPro files.)
Then make a 1 page FusionPro file, make your text frames and fill in your numbers.
Make a graphic rule for the front, something like..
var ImagePath = "/Volumes/Jobs/MyJob/"; // this shows a Mac path not PC
var ImageName = "Ticket " + Field("Ticket");
return CreateResource(ImagePath + ImageName,"graphic",true);
and a rule for the back
return Resource(Field"BackVersion");
