We have an issue of duplicate data using FDM 4.9.34. When we run in 4.9.13, we don't have the issue.
The issue was found in SQL SERVER on INTEGER data type. The issue is when we run the masking on all the tables that need to be masked in 1 « csv » file.
When we run the masking in separated « csv » for the table in error, we don't have the issue of data duplicate.
Release : 4.9
Component : CA Test Data Manager
FastDataMasker-18.104.22.168. has the fix
