Problem with woocommerce variation?

Question

WordPress

I am currently working with the WP ALL IMPORT plugin, everything is fine except for one, I have two attributes transferred differently (one is taken from csv and the second for each product is a list from the function (that is, csv does not have this data) I do them through the function and pass it to the import) - the plugin copes with this, everything is transferred BUT
For some reason, the attribute that I make through the function is not shown on the product page until I go to the product settings in the admin panel and in the variations tab I'll click save changes, after these steps everything appears and works as it should. I started looking for some functions that will do the same as the button does - saves variations, all I found

WC_Meta_Box_Product_Data::save_variations( $product_id, get_post( $product_id ) );

- Not suitable for the reason that a post request is needed here along with some other necessary parameters in it, maybe there is some kind of plugin? Ready solution, can someone tell me?

Answer 1

Add to your function after setting the attributes
wc_delete_product_transients( $product_id );
