Is there a workaround out there that would allow the system to generate a negative charge on a project task? Negative transactions should create a negative charge on those tasks that are chargeable. This should generate negative revenue to back out the revenue previously recognized. And this negative charge should be available to pull onto an invoice. Currently we are creating credit memos to accomplish this which creates more work for our revenue accountants. I know there is an enhancement request out there, but wondered if anyone has found a solution.

Can I ask, what is the underlying use case is that you are trying to solve with this possible workaround?

it seems the best way is to create a SO from project and then > Return Authorization for the negative charge if this is refund or similar related. Return Authorization will create proper revenue recognition, and yes, you would still have to merge, Would love to hear how others deal with that.
