Modify the Break Key in DQM for SAP 4.0
You can change the match code format that is used to generate the break keys by adjusting the substitution parameters in Data Services. In this DQM for SAP 4.0 example, create a new record to test the break key. In Data Services, confirm that MATCHCODE3 is the current format, change it to MATCHCODE1, review the custom function for MATCHCODE1, go to the Data Services Management Console and restart the Break Key service. Finally, create a new record and make sure the match code is created based on the new rules.
