1. PBL dependencies
Select a PBL, and use the button PBL Dependencies to see all the PBLs related to the selected library. This macro is similar to a called hierarchy, but at PBL level.
2. External Dependencies
Select a PBL, and use the option External Dependencies to get details of the items called outside of a PBL. In the screenshot below, see how w_resp_customer_search is calling various items from other PBLs outside of demopfc.pbl
Use the parameter option (wrench) to filter the kind of references you wish to display.
