Data not being imported from external sources

Question: I have used the Import from external sources data processor, after the data was read, and I got the number of rows created and the message that everything was created successfully, Why there is still some missing data in the elements created?

Answer: The import process creates new items in the catalog from which the data processor was opened, let's take notice, that not all attributes related to an item live in the same catalogs, for instance some attributes can be references to other catalog items.

For example, Product's category is a different catalog than Products catalog, so when importing Products data, the import process will try to map the category to an existing one, but if it cannot find the reference to it, it will still create the item for the Product catalog, but it won't create the new Category if this one does not already exist.

This is a way to keep data consistency throughout the 1C:Drive application, but this process can be customized developing an extension.
