Sync error correction#136

Correct sync error cuases at source. Sync errors seem inevitble based on system setup. If the system is set to disallow mismatched sub vs. location invoices to sync to netsuite after payment, why allow the mismatch to flow through during review stage. 2. If having a third item line on an invoice will create a sync error after an invoice is paid, why allow it during review. 3. whatever correction is needed, should be required at review stage not after invoice has gone through all approvals and paid.
