One Microsoft Dynamics GP Client workstation has lost access to Sales / Receivable data.
The data is not available in either Inquiry Screens or Historical Aged Trial Balance Reports.
Financial Data (Accounts Inquiries etc,) can be accessed from this same workstation.
This occurs when the user is logged in, as well as when the 'sa' user logs in on this workstation.
The data can be accessed from other workstations, without regard to which user is logged in.
