You can only see the data and get the error report in SAP Information Steward. So, it is a read-only thing in SAP Information Steward. If you are using Syniti Data Quality, you can see the error and fix it by directly configuring Syniti Data Quality to write back to SAP. Syniti Data Quality allows you to update the source system. In SAP Information Steward, you can't upgrade the source system. You can just see the data and go on to the source system manually by logging in to SAP, and then you have to fix those errors. With Syniti Data Quality, you can integrate SAP and directly fix errors from Syniti Data Quality instead of logging into SAP and then fixing them.
