### Use case

This transformer is used for scenarios when you need to update every entity from a storage.

### Guide

Here is how you can implement the transformer:

Step 1: Create a new transformer and select the “Data, transform data using mappers and conditions” option.

Step 2: Select Data transformer to “Update a storage entity”.

Step 3: Select for which storage an update is needed and input the storage entity identifier.

Step 4: In case the identifier doesn’t exist yet in the storage but you would like the transformer to add a new identifier automatically, use the “Automatically add entity” checkbox.

Step 5: Fill out the “Data to update in the storage entity” field.

Step 6: Save the transformer.
