Propagate Documentation Checkbox (Deprecated)
Talend Data Catalog supports the propagation of documentation (including Name and Business Definition, diagrams, join relationships and custom attributes) from older versions of a model. This propagation of the documentation is now always enabled Thus, when you check the Propagate documentation checkbox, Talend Data Catalog does not change behavior, and documentation changes made to any historical version are still propagted to new versions.
If you leave this checkbox unchecked, the same behavior is true.
This feature can produce conflicts and unexpected results. For example, when you edit the same piece of documentation in different versions the latest edit wins. It is true even when you edit the latest version first and an old version later. You should disable the feature after you finish making future-proof changes to older versions to avoid unnecessary conflicts.
