I get this issue when there is an Object Data table already defined in the drawing that has different Data Fields, or in an external reference drawing.
Firstly I would check in the current drawing if the Object Data table has already been defined.
Run the command adedefdata
This will bring up the Define Object Data dialogue.
Click on the Table: drop down and look for the name MVP_AFC_ATWS
If it exists, select it - Click the Delete button at the bottom of the dialogue. (this will delete the Object Data Table Definition)
Try reimporting you shape file
If it is not found, and you have external references attached, open each and run through the same process.
It is a pain when a drawing you attach has the same object data table and you have to go in and delete it. 😞
I hope this helps.
