Hello everyone, hope someone will be able to help since i am new to all of this.

I have a contract line with only one task of a project associated to it. There was revenue from OTL transactions recognize already on the contract line. The transaction on the other task was not recognized so i deactivated the project task associated to the first contract line as well as giving it an end date. Finally, i created a second contract line and associated the whole project to it, resubmit my contract and approved it.
