EBS 12.1.3 Data masking issue with 184.108.40.206
I tried to data mask the EBS 12.1.3 data with database version 220.127.116.11. but After i masked, I can’t open the application because of SYSADMIN and Guest user was missed. So I raised SR, As per support we need to upgrade database version to 18.104.22.168 otherwise we need to do backport activity. If your database version is 22.214.171.124, you need to check with Oracle support before you do data masking.
I upgraded to 12c, it’s working fine.
