In Chapter 4, Rules we learned that you can use aliases to reference a dimension element in your TI process. Let us look at a practical example. Let us suppose that a company does forecasting on a monthly basis. Each month a new version of the working forecast is created. For example, in January the forecast consists of 12 months of forecasted sales (January through December). In February, the working forecast consists of one month (January) of actual sales data and 11 months of forecasted sales (February through December). In March, the working forecast consists of two months (January and February) of actual sales and 10 months of forecasted sales—and so on. In this example, you can define an alias attribute on the version dimension and use it to refer to whatever version of the forecast is currently running (or is the working version).
Then, TI processes can refer to a version as the working forecast (the alias) and always connect to the correct version...
