We need a magento module that allow to make different import product database profile.
Each profile can be configured with a source (like csv file joigned, or xml), we can easily configure each column to the matching product attribute on magento.
We can define that a column is only for an attributes in one view (if the description is in english, it only complete our default view, if description is also avilable in deutch, the module complete our deutsh description view).
We can complete all missing attributes on csv or xml by default value for this profile (like warranty, etc...)
We can select an attributes on csv or xml and make action on magento database (like original attributes Qty >=1 -magento stock status is : In Stock)
We can select one original attibutes, to update some attribute in our magento database (like Qty, is used to define stock status and qty in stock (for example))
We can compose some attributes (like source url for pictures, for exemple with file joined we need : http://www.xxxxx.com/supreme/images/xxART-NR-FROM-DATABASE-big.jpg)
We can select only some products to import. And can match a product of CSV or XML file with a product already in our magento database.
After inserted, the module auto update price and availability from this file with a cron task (with defined parameters in prodfile status). Period must be defined trought the configuration page of this module.
Original attributes are data from csv of xml files.
Magento attributes are data that we need or that we have in our magento database.
Hope that you understand all i need. Do you know if an extension already exist?
