Cost Transparency application setup With cost transparency, you can determine the allocation rules and run them automatically for all data in the future. Start with associating data sources to cost models. Use data source for bringing additional columns for cleansing or bucket split by enabling the ‘Used by cleansing’ option under data source field maps. Cost modelsA cost model is the set of rules, methods, and metrics that tell the application how to allocate expenses to the accounts in the IT chart of accounts. Allocation metricsAllocation metrics contain additional instructions that the application uses to allocate expenses based on a weighted calculation or on a script. Allocation methods use metrics to perform the allocation.
