Reversal cannot be posted (system error)

What causes this issue?

Error when system tried to read line items being reversed.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

When you reverse a posting that originated during the transfer of
balances during the asset data transfer, use transaction OASV (FI-AA
Customizing "Transfer balances"). Manually create a reverse posting
(with reversed positive/negative signs) for each line item in the
document you want to reverse. If it is no longer possible to use
transaction OASV, use transaction ABF1.
If the problem cannot be solved in this way, contact the SAP Hotline
for assistance.
