Why is the Web Data tab missing from a product's details page?
If the Web Data tab is missing from a product's details page, it's likely the product isn't configured as a web product.
Enable web product status by selecting Actions > Edit Product, and checking the Web product box. If your data is controlled in a primary environment, reach out to your organization's data management team to request they enable web product status.
For more information, see the article How to enable web product status.
