Can't Delete - Related Tables Missing

[Ron Cates]

I am not sure if I am missing something obvious but this situation has been popping up frequently lately. I try to delete a record and it comes up with a message that says "This operation cannot be performed because one or more required related tables are missing. It seems as though this has just started happenning lately in multiple areas where I have never encountered any problems deleting before. If anyone can shine a light on what this is all about it would be greatly appreciated.

Thanks

The only thing that comes to mind right off is to go to the relations screen under manage database and see if the tables are in fact still there, and that the relations are still connected. If you have been making changes to the database itself and maybe deleted a table???
