Cost Allocation Methods in Anaplan

How many of you have developed, are using, or plan to develop and use a cost allocation model? I built a system for the allocation of our internal service funds as part of our annual budget planning model, including allocation statistics and Salary and Wage analyses, and am now working to complete the ICAP/General Fund overhead allocation system consistent with Circular OMB A-87. It would be great to see how you went about building yours, share ideas, or see if anything I have developed could be of use to you.
