When you deploy your BCS nodel and try to update/create your entity, the updatercreator form will show you below error.

The Field named ‘myEntityID’ is provided as input but cannot be found on the ‘Updater/Creator’ method signature for Method with Name ‘UpdatemyEntity’ on Entity (External Content Type) with Name ‘myEntity’ in Namespace ‘myBDCModel’.
