I am in SRM 4.0 version using ECS.
My requirement is to upload a file from the presentation server and the data should sit in the corresponding fields. This has to be done using ITS.
I have created the custom fields for this in the Shopping cart screen at the item level. Now my task is to upload the file which contains data which has to sit in the custom fields.
Let me know, where I have to write the code for this and to upload the file in ITS what are the steps.
Your inputs in this regard is appreciated.
