Hi,
Let me know whether your report was edited by Excel. If it’s, this problem seems happened when you import an Excel report into an DB. According to my research, I would give your following suggestions:
- Deleted all empty columns and rows in Excel as the reason that the Excel spreadsheet is not allowed to contain any references to the associated Auto Number column in the DB.
- Try to check your spreadsheet to make sure that the data type in each column matches with the data type format in the Access DB columns. In addition, highlight all columns and then select the command to "unhide columns" in the format menu.
- If above is not useful, you can try to import the spreadsheet into a new table rather than appending it to an existing one.
- Try to click options of Excel and select "allow this content".
Anyway, this issues seems caused by Excel problem. If above solutions are also not useful, I suggest you can post your issues
to Office Forum to get more professional help.
