Dear all,
Background:
there was a "global withholding tax" feature enabled, i used item withholding tax on released product, now i removed this feature, so now system gave me following error whenever i update any information on released product.

so when i gone into deep, i realized that the target fields (through data management framework > data entities) available on released products v2 are different from those when global withholding tax was not enabled before, highlighted rows are additional fields.

so i need to remove these two fields from target fields, how we can remove it, because delete button is disabled.
