Applying a New Price Coefficient TV Across a Large Catalog

Adding a new dropdown TV to a catalog with two thousand or more products is not really a field-definition problem. It is a migration problem. The moment a new coefficient such as prod_rate is introduced, the team needs a way to populate existing products reliably.

Doing that page by page in the manager is usually the worst option.

A better rollout strategy

• define the TV values clearly and keep the allowed options stable,
• prepare a bulk update path for existing products,
• default new products to a safe value,
• use import or database-level tooling for the initial migration.

This is especially important when the field drives price calculation. A half-filled coefficient field means catalog prices can become inconsistent immediately.

For large catalogs, TV rollout should be treated like schema evolution: decide the default, prepare the migration, and only then depend on the field in pricing logic.
