Hallo Frank, ich habe in der Datei /admin/html/compatibility/product/product_master_data.inc.php den Code: Code: // Artikelnummer generieren if(!$pInfo->products_model) { $my_product_id_query = xtc_db_query("SELECT MAX(products_id) AS products_id FROM " . TABLE_PRODUCTS . " "); $my_product_id = xtc_db_fetch_array($my_product_id_query); $my_product_id = $my_product_id["products_id"] + 1; $pInfo->products_model = "Art-".$my_product_id; // Art- kann editiert werden } in Zeile 96 gepackt.
