Thanks for the tip. I have found 0 ID and I have issued it manually. I have tried to check the option AI in the table si_invoice_items column ID. I can not. SQL error message says “Cannot change column ‘id’: used in a foreign key constraint ‘si_invoice_item_tax_ibfk_2’ of table si_invoice_item_tax
Well, I could not find this named column in the table and I do not know waht to do after this new message.
