Cannot edit a record in Sales Orders error in Credit Note

Guys please help me in this one. I encountered an error upon invoicing credit note. here’s the path: sales order>>sales order line>>sales order line fasttab>>select credit note>>select a credit note voucher>>click OK

everytime I click ok, I encounter this error saying that "Cannot edit a record in Sales Orders(Sales table). An update conflict occured due to another process deleting the record or changing one or more fields in the record.


I already tried to restart the data usage of this ff user but still the error exist. I also perform a successful SQL sychronization, compilation and Full CIL . Thanks in advance
