Since you brought the topic of migration, sometimes the selections which takes References would be needing a reset.
in your template (configured in Excelimporter), can you check if all the options are properly selected?
May be it is worthwhile have a simple excel importing drill first and then move on to debugging the existing templates.
Good luck
Hi Sai Anusha Janapamula,
I have same problem. I don't know if this is a bug from mendix or not. I have checked the whole configuration in excelimporter, all is stable. However, when using excel file with .xlsx format, it doesn't work. I created a new excel file, copied the data from the old file and saved it in .xls format. Unexpectedly, it worked fine.
You can try it.
