The tables for launchpad configurations are pretty complex, but feel free to look into them: WDY*
Role <-> Catalog - AGR_BUFFI; Put the catalog in the URL field and make sure it is surrounded by * since it contains the full id, not just the one entered on creation.
To see in which catalogs and roles certain target mappings are located, you can use the transaction /UI2/FLIA and put your target mapping in the Intent field. It supports pattern matching so you can check for example all actions for a certain semantic object.
Hope this helps,
