Import/export component of goods in virtuemart 1.1.9 in YML format
Requirements: Availability of process visualization. Goods should be transshipped in any quantity, in any category. There should be a visually ascertainable match in the component between the categories in the YML file and the store categories and the possibility of adjusting positions. About: exported the file. I made a correction on prices or the amount of goods in stock and again poured on the site.
