Procedure bodies are not stored here (D10). The call sections above are our own, per object, from the BC29 call graph. For a procedure body or the calls of one procedure, ask bc-code-atlas (external, by Stefan Maron, MIT; default corpus w1-28), which the bc-observatory plugin connects: bcatlas_resolve_node(object_type: "codeunit", object_name: "Purch. Availability Mgt."), then bcatlas_get_procedure_body or bcatlas_get_neighbors on the returned id.
