Working with CSV transformations, version 4.6.6.6.


The process begins with the selection of the container pertaining to states and regions within the CSV data source, followed by the initiation of transformations. A new transformation is created, and its name is adjusted to adhere to the standard protocol, named "Dimension Transformation Trait - Transformation of States and Regions."


Upon inspection of the preview, it becomes apparent that the state code and descriptor already exist in the source table, while the region data requires encoding through the LOCAP logic. The first step involves creating a LOCAP reference table, achieved by accessing the SQL Server Data Container.


It is noted that the Data Warehouse lacks a specific regions table, necessitating the extraction of the relevant fields from the Customer dimension to construct the LOCAP reference table. Subsequently, the LOCAP process is applied to map region descriptors to their corresponding codes.


However, an attempt to apply the LOCAP logic directly to the states and regions transformation reveals an issue with repeated entries, rendering the LOCAP process ineffective. Consequently, a decision is made to create a separate transformation specifically for regions.


The new transformation, focusing solely on regions, undergoes several steps, including the removal of duplicate rows and the application of the LOCAP process to establish accurate mappings between region descriptors and their respective codes.


Despite successful implementation within the isolated transformation, the need arises to integrate these region mappings into the primary transformation. This integration will be accomplished through a Join operation, aligning the region data with the existing state data for seamless incorporation into the final dataset.


The complexities of this integration process necessitate a separate video tutorial to ensure clarity and thoroughness in execution. Thus, the forthcoming video will delve into the specifics of merging these transformations effectively.


Thank you, and stay tuned for the next installment.
