I need help because I’m freaking out.
I have a relationship field, from woocommerce products I take a custom post type called SERIE, so the ralationship is product and serie.
Serie has more taxnoomies fields, and its are the attributes of woocommerce.
I need 2 solutions and only one work for the moment.

CASE 1 : inherit taxonomies when save a product
When I create a new product, I connect the product with a SERIE throught a relationship field and when I save post, the new product inherit the taxomies of SERIE.
So I developed a function in functions.php and it works!

add_action('acf/save_post', 'update_post_meta', 20); 
	
function update_post_meta( $post_id ) { 
		
$post_type = get_post_type($post_id);
		
global $product; 
if ( 'product' == $post_type ) {
					
//TAKE RELATED INFO IN POST TYPE WITH RELATIONSHIP FIELD
$posts = get_field('serie_di_appartenenza');
if( $posts ): 
foreach( $posts as $p ):
//FIRST TAXONOMY
$scrittore=get_field("scrittore_appartenenza", $p->ID); 
if( $posts ): 
foreach( $scrittore as $s ): 
$scrittore_ereditato= get_the_title( $s->ID );
	
//ADD INFO IN GLOBAL ATTRIBUTE WOOCOMMERCE				
$term_taxonomy_ids = wp_set_object_terms( $post_id, $scrittore_ereditato, 'pa_scrittore-woo', true );
					
endforeach;
endif; 
endforeach;
endif; 

//ADD INFO IN CURRENT POST

$data = Array(

'pa_scrittore-woo'=>Array( 
'name'=>'pa_scrittore-woo', 
'value'=>$scrittore_ereditato,
'is_visible' => '1',
'is_variation' => '1',
'is_taxonomy' => '1'
),
);

//UPDATE META					
update_post_meta( $post_id, '_product_attributes',$data);
					
}
}

CASE 2 : update taxonomies info of products when I update the serie custom post
Foe example, I’ve already created the custom post SERIE and I want change the value of taxonomies. When update the post I want update all taxonomies of products connectes with relationship field.
I developed this function in functions.php and it doesn’t work !

add_action( 'acf/save_post', 'aggiorno_attributi_prodotti_correlati' , 1);
	
function aggiorno_attributi_prodotti_correlati( $post_id ) {
		
$post_type = get_post_type($post_id);
		
global $product; 
if ( 'serie_prodotti' == $post_type ) {

global $product; 
// get products connected
$doctors = get_posts(array(
'post_type' => 'product',
'posts_per_page' => '-1',
'meta_query' => array(
array(
'key' => 'serie_di_appartenenza', 
'value' => '"' . get_the_ID() . '"',
'compare' => 'LIKE'
)
)  
));
			
if( $doctors ): 
foreach( $doctors as $doctor ):  
					
//TAKE RELATED INFO IN POST TYPE WITH RELATIONSHIP FIELD
$posts = get_field('serie_di_appartenenza');
if( $posts ): 
foreach( $posts as $p ):
//FIRST TAXONOMY
$scrittore=get_field("scrittore_appartenenza", $p->ID); 
if( $posts ): 
foreach( $scrittore as $s ): 
$scrittore_ereditato= get_the_title( $s->ID );
	
//ADD INFO IN GLOBAL ATTRIBUTE WOOCOMMERCE				
$term_taxonomy_ids = wp_set_object_terms( $doctor->ID, $scrittore_ereditato, 'pa_scrittore-woo', true );
					
endforeach;
endif; 
endforeach;
endif; 

//ADD INFO IN CURRENT POST

$data = Array(

'pa_scrittore-woo'=>Array( 
'name'=>'pa_scrittore-woo', 
'value'=>$scrittore_ereditato,
'is_visible' => '1',
'is_variation' => '1',
'is_taxonomy' => '1'
),
);

//UPDATE META					
update_post_meta( $doctor->ID, '_product_attributes',$data);

endforeach; 
endif; 
					
}
}
