I have a schematic design that contains several hierarchical blocks, referencing external schematics. If I generate the BOM for the entire design, Orcad correctly descends into the hierarchical blocks and reports the occurrences of all the components. If I try to do the same thing for a selection of the design (i.e. only one page or some pages), Orcad doesn't descend the hierarchical blocks anymore and reports only the "local" parts, ignoring the parts contained in the hierarchical blocks. A similar thing happens with the "browse parts" command.
What am I doing wrong? Is there a way to generate the BOM (or to browse parts) only for a portion of a hierarchical design?
