I have a new company set up in Sage 200 and need to upload the opening sales invoices into the debtors ledger.

As we use all 20 analysis codes on the sales ledger we’ve been advised to upload these via the SOP as a normal import doesn’t capture the analysis codes. 

However when you import into the SOP it creates the sales invoice with a date of today, and not the date of the original invoice.

Does anyone have any solutions on how to import sales invoices and their analysis codes into Sage 200 without it changing the invoice number and the invoice date?
