Are you exporting all 26 tables? If you do this every table will be on a different tab in the excel workbook.
I would recommend only exporting the tables you want to use.
Do the following
- Navigate to Configuration Packages
- Click on DYNAMICS365 config package to go into it
- Select the 'Purchase Header' line - (click the 3 dots so you can do 'Select More')
- Make sure both 'Purchase Header' and 'Purchase Line' are selected
- In the options at the top, go under the 'EXCEL' tab (Do not click 'Export to Excel' under the HOME tab)
- Click 'Export to Excel' under the EXCEL tab
- Confirm that the message says "2 tables have been selected. Do you want to continue?"
- Click 'Yes'
- Fill in your Purchase Header and Line data
- Import from Excel and Apply data - Fix errors
Thanks,
