Hi
Invoice correction Request is a combination of Credit memo Request and Debit memo Request, which has got Item category G2N and L2N respectively. They have opposite signs to one another.
That means, each item is duplicated as Credit posting and Debit posting with opposite signs as you can see in the Overview screen.
Therefore, initially the Net value is "Zero", as there is no difference.
Now, you can make the correction / changes via the "Debit memo" items only. You can not make any changes through the Credit memo items (they are disabled area).
If, you want to change the quantity, you can do it in the Overview screen itself.
If, you want to change the Price, then select the item > go to item details > select "Condition" tab and make the chages here > come back to the overview screen.
Now, click on the "Delete unchanged pair" button in the application tool bar.
System will delete the unchanged pairs and only the changed pairs will remain.
The resulting difference (of Credit item and Debit item)  will  be automatically reflected in the "Net value" field for which you have to issue a Credit memo to the customer.
