SLA Mapping for WIP Variances in Cost Management

I'm looking for a way to derive the accounts for the WIP Variance event class, Work in Process Variance JLT for the resource and overhead variances by using information from the Resource and Overheads that are applicable for the discrete job. Everything I've tried is not working when running create accounting or is giving me an error when I try to validate the AAD that the says the ADR's assigned to the JLD's user sources in their conditions that have not been assigned to the event class. Has anyone found any sources that will work for this?
