Adjust sales cost after post sales invoice

Hello,

Yes, this is my problem now.

We need to adjust for each invoice line.

In addition, if I try adjust the transaction in inventory close/adjustment. But after I make adjustment on my sales issue, AX does not update my COGS on my Sales invoice.

I believe my case is very common – to adjust the post sales invoice for COGS value.
Any suggestion/idea?

Thanks in advance.
