Tell us what you are trying to do?

I am trying to programatically creating a WooCommerce product + create a translation of this product.
I can do so with a normal post, but if I do it with a WooCommerce product with an SKU, it says: "Invalid or duplicate SKU".

Is there any documentation that you are following?

Is there a similar example that we can see?
$default_language = 'en';
$product = new WC_Product();
$product->set_name('A product in orignal language');
$original_post_id = $product->save();

$default_language = 'da';
$product = new WC_Product();
$product->set_name('A product in translated language');
$post_id = $product->save();

$original_post_id = apply_filters( 'wpml_object_id', $original_post_id, 'product', false, $default_language);

$wpml_element_type = apply_filters('wpml_element_type', 'product');
$get_language_args = array('element_id' => $original_post_id, 'element_type' => 'product' );
$original_post_language_info = apply_filters( 'wpml_element_language_details', null, $get_language_args );

$set_language_args = array(
'element_id' => $post_id,
'element_type' => $wpml_element_type,
'trid' => $original_post_language_info->trid,
'language_code' => 'da', // create "Danish" translation
'source_language_code' => $original_post_language_info->language_code

do_action( 'wpml_set_element_language_details', $set_language_args );

Hello and thank you for contacting us.

The SKU usually has to be unique, and that is why we have custom logic that syncs that for the translations.
When creating programmatically a product, perhaps it is best if you leave the SKU empty and if I recall correctly, the SKU should sync.

Another way probably is to use our REST api as noted here:

And another way is probably to duplicate to the translation using our hooks as noted here:

My issue is resolved now. Thank you!

I ended up adding

add_filter( 'wc_product_has_unique_sku', '__return_false' ); 

Before importing, and that fixed the issue
