Summary: Create a set of baskets for a single application (alternative: for all applications). Each basket contains all DSNs defined in application administration as production DSNs, baseline DSNs or promotion DSNs. Read more »
The above screen (via Appl id within Target selection) shows that this solution can be used for just 1 application, or for all (dozens? hundreds?) applications in 1 shot.
Also note that this solution (via Site within Target selection) can be used to process "ALL" sites together, or to process just 1 site (e.g. a new promotion or production target added in various applications) and eventually to be repeated for a 2nd site.
To understand how the output of this solution looks like, and how to further process that output, checkout the various steps in the scenario below.
