I’ve been trying to use the Opening Invoice tool to record the sales invoices for my accounts receivable opening balance. i have used it with purchase invoices with out any problem but when i try it with sales invoice type, i get an error “Please select customer first”. I have selected the correct customer as my entry for the party field but the error persist.
