clearMDM version 1.12 introduces Custom Rollups for Text Fields. Previous versions supported numeric fields only. Text field rollups provide the capability to bring notes or reference value data together in a single field on the master record. This new feature has been added in line with customer feedback and is intended to support use cases requiring a complete at-a-glance view at the master record level that includes text data hidden (one or more clicks away) at the transactional level.
Future enhancements in this area will include addition of support for Date Fields plus additional aggregate functions.
