There are multiple possibly reasons, including the one ArnelGP cited.
However, there was a recent bug released by MS that caused this problem in Access relational database applications linked to SQL Server or MySQL databases. If your situation involves SQL Server or MySQL databases, perhaps it is the reason for the problem. That said, this particular bug was supposed to have been fixed, so it may not be involved. Please verify one way or the other
Also, the more details and context you provide, the more likely someone will be able to offer pertinent suggestions, so please round out the description of where, when and how this error appears. Thank you.
