I'm fairly new to Enterprise One. Most of my users including me can't export grid data to excel.
We can export up to 200 rows but not more than that. About 2 months ago there was no problem with that.
you need to provide your tool release level.
By the way, if you are on 8.96 there is a settings on jas.in-> ImportExportErrorLimit=xxx
You need to ask for it to your CNC.
