Hiding Consistency Check Warnings in RPD

We can hide selected warnings from the Consistency Check Manager. Just follow below steps.
1.Go to the following directory
ORACLE_INSTANCE/config/OracleBIServerComponent/coreapplication_obisn
2.In that directory, create a text file called warn_off.ini. This file must be in ASCII format.
3.List the warning numbers that you want to add to the exclusion list in the Consistency Check Warnings dialog:
[CCOptions]
CC_WARNINGS_LIST = 39024,39077
Note the following:

• All excluded warnings must be on one line and can be separated by a comma, a semicolon, or a space.
• You cannot exclude errors. You can only exclude warnings from the Consistency Check Manager.
• If you add warning numbers from the default exclusion list (39009, 39054, 39055, 39057, and 39059), they are ignored.

4.Save and close the file.
5.Close and then re-open the Consistency Check Manager. The new warnings appear in the Consistency Check Warnings dialog and are selected by default, meaning that those warnings will be excluded from consistency checks.
