Currently, it is set in our catalog business rules that a KIT SKU's freight weight should be defined by the sum of its components - https://help.vtex.com/en/tutorial/cadastrando-kit--tutorials_215

However, it is currently possible to overwrite this weight calculation via API and or webservice where the value set is the one directly sent in the payload, not considering any component weightage.

1. Create an SKU KIT and components for it;

For example, the component's original weight can be 100g and the kit is composed of 6 items of this unique component. Consequently, its final weight should be 600g:

Even the input box is set as a readonly.

2. However, if in the SKUKIT structure, that is, the form that composes the kit's information, I fetch this data via API or webservice, such as:

curl --location --request GET 'https://merch.vtexcommercestable.com.br/api/catalog/pvt/stockkeepingunit/310118469' \ --header 'Content-Type: application/json' \ --header 'Accept: application/json' \ --header 'VtexIdclientAutCookie: ' \ --header 'Cookie: janus_sid=361dacc3-e2b8-4ee1-8f5b-b2cf0529f39a' \ --data-raw ''

3. And then directly update the related JSON property, sending it via PUT Method in the payload:

The previous value that took into account the component's weight * amount is completely overwritten, consequently generating possible inconsistencies in the freight calculations.

Updating the component weights only and letting the application calculate the final kit weight by itself.
