If the plug adjustment is made manually, therefore, the balance sheet may be thrown out of balance. OFA can be set up to automatically calculate the plug to balance the balance sheet while also recalculating the interest expense. Implementing OFA When building an OFA application, the developer must create and populate its various components. The majority of application development tasks can be performed from a Windows client using menu options in the Administrator workstation. Hierarchies allow aggregation of data to higher levels of summarization and facilitate drill-down to detail.
Dimensions can have multiple hierarchies.
OFA takes advantage of Express' multicube architecture allowing FDI dimensions to reflect their real-world business dimensionality. For example, a Salary Grade table will have different dimensions than Actual, and Planning can take place at a higher level of detail or over fewer dimensions than Actual can. Models are nonprocedural, which means that Express will determine the correct order of execution regardless of the order of the equations - useful when creating or making changes to existing models. Models can also solve simultaneous equations. This capability can be useful, for example, to a company forecasting its balance sheet.
