Expired license

Integration Issue: payslips
The most comment integration issue for payslips is when INSUFFICENT_PERMISION is reported. This usually means the the nomincated MyPay Integration User in NetSuite does not have permission to access the File Cabinet folder where payslips are stored. Please check the permissions (e.g. Group Permissions) on the folder in NetSuite.
