What is an invalid method for updating dimensions in PCMCS?

Using manual entry for dimensions is considered an invalid method for updating dimensions in PCMCS because it lacks the consistency and accuracy that automated methods provide. PCMCS is designed to manage large sets of data efficiently, and manual entry can introduce errors and lead to discrepancies in reports and analyses. The system encourages methods that allow for bulk changes and maintain data integrity, such as importing new dimension files or using the action menu to update dimensions.

Furthermore, revising rules is a necessary function in PCMCS for ensuring that data relationships and calculations remain accurate as business needs evolve. Each of these valid methods supports the overarching goals of efficiency, accuracy, and robust data governance, making manual entry an unsuitable option in this context.
