When one project references another, all items in the referenced project are available for reuse from the main project.
When you import analyses from a reference project into a local project or a remote project which does not connect to the same reference project, you will have problems opening the analyses and running them. This is because only analyses are imported without their items. You must first create the connection to the same reference project before being able to correctly use the analyses in the current project.
Before you begin
- You have read-writing authorization for the main and referenced projects. For further information, see Talend Administration Center User Guide.
- You have opened the main project in the Studio.
From the main project, open the analysis on which you want to use an item from
the reference project.
In this example, you want to use a business rule age_18 defined in the reference project on a table analysis from the main project.
Drop age_18 from the reference project to the selected
table in the analysis editor.
Items and resources in the referenced projects are always up-to-date since the refresh option in Talend Studio will refresh EVERY item in the studio. However, the refresh operation could be quite long if you have too many references and items in each of your projects. It is therefor preferable not to use very big referenced projects, especially if you use the database repository.
- Run the analysis.
The table is analyzed against the business rule from the reference project and results are displayed in the editor.
