We’ve had 1 or 2 issues with invoice nos. being copied and pasted from PDF, but occasionally this has resulted in a blank space at beginning, leaving the possibility of processing an invoice twice

Is there anything can be set up to stop blank spaces at beginning of supplier invoice number?

Hi ​@SMcLees,

You can enable a validation for Invoice No field in the Page Designer which will check if there is any leading space with entered Invoice No. 

Please refer to the screenshot below.

Validation syntax - substring(InvoiceNo, 0, 1) != " "
