About

Before building a rules file, you must decide whether the rules file will be used for :

Use same rules files when

Use the same rules file for both data load and dimension build if you plan to load the data source and build new dimensions simultaneously.

Use separate rules files when

Use separate rules files for data load and dimension build under any of the following circumstances:

  • To build an outline from scratch
  • To perform different field operations during the data load and dimension build
  • To reuse the data load or dimension build rules file separately
  • To use data sources that contain no data values, only dimensions

Restrictions

Once you create a rules file, you cannot separate it into two rules files. Similarly, you cannot merge two rules files into one file.
