When paying an invoice linked from a GRN I was unable to get the VAT on the invoice to balance with the amounts generated within HCSS. This threw the total amount out on the invoice and although I tried to amend the VAT within the invoice screen, it reverted back to the wrong amount again once submitted. I then had to reverse the invoice linked to the PO and GRN and create a non order invoice to process the invoice. The VAT tolerance was changed but this made no difference. Any ideas?
Are you sure this is the HCSS you are trying to reach? We are on the construction side in the US. It sounds like you may be trying HCSS in the UK.
