Returning Customer Goods - Partial Returns and other questions

As advised by the following Sage City Blog Post (Thanks by the way)  re: https://sagecity.na.sage.com/ca/sage_businessvision/b/sage_businessvision_blog/posts/tips-and-tricks-returning-customer-goods , we tend to do negative cmtd qty returns for our returns to balance out inventory and the books.  My question is, is this the acceptable practice for partial returns?  

Example:

  1. Customer Purchases Product #0, #1, #2, #3
  2. Customer visits the store 5 days from now, and wishes to return Product #0, and #1
  3. If I were to look at the original invoice and create a copy as a reversed order (see linked blog article), all items would be reversed but in this instance only 2 items are being returns and I want to put them back into inventory.  

Thus, should I create a new Work Order (Order Entry) for that customer, add in Product #0 and Product #1 and submit negative cmtd qty's?  i.e. Order Entry (Customer A) - Product #0 and Product #1 with negative commited quantities.  i.e. "Credit #1"


How about balancing the books, can I or should I link all three ledger activities together ?  i.e. Unlink the original invoice with the payment that was successful (i.e. Invoice #1 and Payment #1 - original purchase).  Now should I link Invoice #1, Payment #1, Credit #1 ?  Should I be creating some sort of transaction or "payment" history to link as a fourth item that includes the authorization number or something of the return amount ?

Any help appreciated.
