Hi
try this way
$item = array(
'Name' => 'Product A',
'Description' => 'This is my test product A',
'SKU' => '10085WE',
);
$user_id = get_current_user(); // this has NO SENSE AT ALL, because wp_insert_post uses current user as default value
// $user_id = $some_user_id_we_need_to_use; // So, user is selected..
$post_id = wp_insert_post( array(
'post_author' => $user_id,
'post_title' => $item['Name'],
'post_content' => $item['Description'],
'post_status' => 'publish',
'post_type' => "product",
) );
wp_set_object_terms( $post_id, 'simple', 'product_type' );
update_post_meta( $post_id, '_visibility', 'visible' );
update_post_meta( $post_id, '_stock_status', 'instock');
update_post_meta( $post_id, 'total_sales', '0' );
update_post_meta( $post_id, '_downloadable', 'no' );
update_post_meta( $post_id, '_virtual', 'yes' );
update_post_meta( $post_id, '_regular_price', '' );
update_post_meta( $post_id, '_sale_price', '' );
update_post_meta( $post_id, '_purchase_note', '' );
update_post_meta( $post_id, '_featured', 'no' );
update_post_meta( $post_id, '_weight', '' );
update_post_meta( $post_id, '_length', '' );
update_post_meta( $post_id, '_width', '' );
update_post_meta( $post_id, '_height', '' );
update_post_meta( $post_id, '_sku', $item['SKU'] );
update_post_meta( $post_id, '_product_attributes', array() );
update_post_meta( $post_id, '_sale_price_dates_from', '' );
update_post_meta( $post_id, '_sale_price_dates_to', '' );
update_post_meta( $post_id, '_price', '' );
update_post_meta( $post_id, '_sold_individually', '' );
update_post_meta( $post_id, '_manage_stock', 'no' );
update_post_meta( $post_id, '_backorders', 'no' );
