Does anybody know what the maximum number of table entries for an iPart is?
When iParts were first implemented we had a limit of 1000 rows for performance reasons. It takes a fair amount of time to parse the table when there are a lot of rows. I would edit the table via the spreadsheet, copy half of the rows to a different workbook, and then test the smaller factory. If it works then you can determine the best way to split it into smaller factories.
