How to create and use data quality rules with SAP Master Data Governance on SAP S/4HANA 1809 (Part 2)

By following the instructions of part 1 you have created a data quality rule that is in status active and ready for evaluation.

Before you continue, ensure that there is corresponding product master data in your system, products that fit to our example score expression products of type finished goods (MARA-MTART = FERT) that also have a product number starting with ZDEMO (MARA-MATNR = ZDEMO*). It is fine to create a few products, for example using the app Manage Product Master Data. It would be nice though if some of the example data comply with the rule and some don’t.

After you are done with this blog series, you might want to have lots of data in your system to experiment with larger and different data sets. Have a look at MDG’s master data consolidation capabilities that also include the upload of master data in CSV or spreadsheet format.
