Data lineage and quality checks have streamlined team-wide collaboration and business context
The biggest friction point or frustration I have encountered with Microsoft Purview Communication Compliance is cost-wise it is acceptable, but sometimes unexpected errors will occur, though this happens very rarely. There are features I wish Microsoft Purview Communication Compliance had that it does not provide today. Enterprise-level lineage is one such feature. As of now, if Microsoft were to provide this tool for free when you buy Microsoft Fabric, I feel that would be better. This would also result in lower license costs. I do not have any changes I would make to Microsoft Purview Communication Compliance at this time.
