There is no native MPN fields in Woocommerce, but there is SKU field.
We usually assign MPN value like this pattern:
custom prefix like “NX” + “SKU” number = NX34534635
I already created a custom field named MPN, but how to dynamically assign value to the custom fields please?
Great thanks in advance.
What do you mean by “dynamically assign”? Will need more information.
Where/When/How are the values being added?
