We want to change some messages from pattern like objects, obase, etc. But obviously we can't because there Plex protected patterns. There is a way to modify the messages, or replace them all across the model?
The requested changes are required in CA pattern library which are locked. Pattern library changes are only carried out in major release of the product, not as a part of PTF build. So we need to consider this request for upcoming release.
As a workaround, user has to write his custom message object(s) and add/replace them in standard layer or all required places.
