This means that the Org Key and Object you have selected are not permissible for use together in that fiscal year. Review the code to ensure you have entered the account code correctly. If after review, the account code is correct as entered, you will need to complete the Account Request Form located at: http://www.spotsylvania.va.us/finance-enterprise or contact the Accounting Office.
Remember that we have Object for things like 'Ammunition' that would be associated with Keys for the Sheriff department but not with Keys for the HR Department. While the account department tries to create all the necessary associations when a Key is created, it is always possible some were missed or not considered.
