Supplier processing

SOLVED

Good day, 

We have recently moved Pastel Partner (PP) to Sage Accounting (SA). In PP, we had outstanding PO and GRN (linked to when creating a supplier invoice). These did not convert when our conversion was done, only the tax invoices were converted. 

Here's my question, is there a way of copying the information on the customer invoice to the supplier invoice and adjusting the prices? 

And also, is there a way of copying the sales order/quotation to a supplier invoice? 

Regards,
