Oracle EBS Data Uploads - what are out-of-box and third-party options

Hello All,

On regular basis, we do get requests to upload master and transactional data to Oracle EBS, examples would be: Cost, Items, Sales Orders, ABC Class list/items, Sales Orders etc. and also update data as well.

There are API's for importing data (would require to customize and develop custom program to take data inputs, import), though my questions are :

1) what is typical process following that you can share as to how this is being done.

2) are there any standard out of box programs, utilities to uploads

2)are there any third-party (free/licensed) products that will upload different data elements
