Associated products do not show in the configurable product, don't know why... though My simple and configurable products are imported without errors but the simple are not attached to the configurable.
All conditions are checked by me..
visibilty = not show inidividually stock = in stock attribute set in simple = same as configurable product price = set status = enable re-indexing -> done ...
I am using the DataFlow import tool..
It is not possible to associate simple products to configurable parents using the 'data flow' import tool.
As you are using Magento 1.9.x you can use the more advanced Magento 'ImportExport' system under 'System > Import/Export > Import'.
See more detail about the Magento 'ImportExport' system on the official documentation pages here: http://docs.magento.com/m1/ce/user_guide/store-operations/data-import.html
And guidelines for importing here: http://docs.magento.com/m1/ce/user_guide/store-operations/data-import-guidelines.html
For more information about the format required to import (as it is considerably different from 'data flow') I would suggest exporting an existing configurable product with associations as reference or read up on articles such as this: https://www.integer-net.com/importing-products-with-the-import-export-interface/
