Can I suggest adding a powerful new feature to the accoMASTERDATA visual: the ability to define and generate a custom composite key using a DAX expression. Feature Details: Composite Key Definition: Introduce a configuration option in the settings menu where users can define their own composite key by selecting one or more TransactionKeys. Flexible Key Composition: The visual should combine the selected TransactionKeys to generate a composite key dynamically—preferably using a DAX formula or expression defined by the user. Automated Matching Logic: The visual should include smart logic to: Detect if the composite key exists in the Master Data Management (MDM) table. Insert a new record if the composite key is not present. Update the existing record if the composite key is already represented—ensuring only the changed values are updated. Benefits: Enables more granular and tailored data matching. Reduces manual data prep and reconciliation steps. Supports complex use cases involving multi-field identification in MDM. This enhancement would significantly increase flexibility and broaden the applicability of accoMASTERDATA in real-world planning and master data scenarios.
