Hi Haritha,
I had a look at the proposal logs for vendor: 1000219 and 1007788.
a) For vendor : 1000219 the system is suggesting it can't pay document: 1700025834 posted in SGD currency since the payment amount is a debit balance. Though you have invoices posted in USD currency system cannot clear documents posted in difference document currency. The solution for this document would be adjust against an invoice posted in SGD currency
b) For vendor: 1007788, The system suggest their is no credit balance for payment. Please check the total items due for payment in payment run dated: 01-04-2013, identification: CREM2 for this vendor.
Thanks,
Sajin
