Values are not correctly pulled into the invoice

Good afternoon [file]19432[/file] An example of an invoice with an error: [file]19432[/file] https://box.agro-him.com.ua/app/document/28840/control/ [file]19432[/file] Order: [file]19432[/file] https://box.agro-him.com.ua/28049/ [file]19432[/file] A couple of times a month invoices are generated with incorrect values. [file]19432[/file] In the "Base price" column, not the prices that should be there are chaotically pulled up. [file]19432[/file] For example, the base price of the product "Roundup 100 ml" is 49.40 UAH, and the price has increased to 47.50 UAH. [file]19432[/file] Moreover, if you create an invoice again, everything will be correct. [file]19432[/file] The invoice is automatically generated at the stage "Doc. discount" [file]19432[/file] Here we created an invoice with the same action later, everything is as it should be: [file]19432[/file] https://box.agro-him.com.ua/app/document/28886/control/ [file]19432[/file] Tell me, please, what is the problem. [file]19432[/file] Thank you! [file]19432[/file] [file]19432[/file]
