How to Delete/Reverse a Project cost causing invalid accounting

Content (please ensure you mask any confidential information):

User selected incorrect BU while loading some misc cost in the projects (cross charge enabled) directly. Now as the ledger of provider BU is not associated with Project BU's ledger, the accounting is failing after the cost is imported and processed. We will not be able to update the SLA rules also for misc cost as it will affect other valid transactions. And reversal adjustment, while reverses the cost, will also results in failure for original as well as reversed cost.
