Error: This absence will decrease for employee's PTO net entitlement to less than zero

 Hi,

I recieved the following message above when attempting to apply for vacation via self service.  However when the accruals are viewed from the core application the net entitlement is more than being applied for.  Currently the employee has an accrual amount + a Infomrtaion element amount which equals the net entitlement however self service is not reading the amount in the infomration element.  Has anyone have this problem and can advise how to fix it.
