Options to Update sales order

Summary:

Content (required):

Hi,

We need to update sales orders. These updates includes Updating Required dates, Delete ISO lines, Add new lines to existing sales orders, Cancel sales order lines.

What are the options available to update sales orders (FBDI / ADFDI / Other??)

FBDI seems complicated as user should fill multiple sheets. Are there any known / previously used user friendly workarounds to update sales orders in Fusion
