Field transformations
Even though all source tables have several features in common, they have some particularities that make it necessary to undergo a set of transformations to harmonize them for the union table. The most common transformations comprise changes in the data type or the application of rules when several columns in the source table feed a single column in the union table. You can find below the detailed list of transformations in each source table.
