Transfer Actual Costs from one task to another (same Project)

Hello Oracle Projects community,

We are in Go-live week and the customer inserted one sales order allocated to Project 01 and Task 10. Then, after the shipping process of the sales order, the costs were transferred to the project via PRC: Transaction Import. That went well.

Problem: this costs should not fall into Task 10; they should have been allocated to Task 20 of the same project.

Question: Is it possible to transfer the costs between tasks?

This is very urgent.

Thank you!
