Reverse entry value set automatically for full reversal

What causes this issue?

The quantity for which you are entering the invoice is the same as the
quantity credited to date. You are carrying out a full reversal on a
quantity basis. In this case, the total credited value must also be
reversed - otherwise you could be left with a value but no stock for
this material.

System Response

The system calculates the total credited value and overwrites the entry
in the field <LS>Amount</>.

How to fix this error?

Check the amount. You may have to post the invoice as a subsequent
debit, so that the quantity credited remains the same.
