FIND MY PARENT SALESFORCE USERS BY ROLE HIERARCHY

Was looking into a blog post of jeff douglas on FIND MY SALESFORCE USERS BY ROLE HIERARCHY, its an awesome utility code for fetching the child users in the hierarchy, so thought of righting a same kind of code to get all the parent users in current user's hierarchy, when I started writing it then I realized it is not that much easily, have to give some time to it.

So here I am, below is the code for fetching the Parent user's id in hierarchy, the method will the return a map of user on the key and the set of Id's of the parent user in the values.

1:public static Map<Id, Set<Id>> getRoleParentSubordinateUsers(Set<Id> userId) {  
2:      Map<Id, Id> roleIds = new Map<Id, Id>();  
3:      Map<Id, Set<Id>> parentRoleIds = new Map<Id, Set<Id>>();  
4:      // get requested user's role  
5:      for(User usr : [select Id, UserRoleId from User where Id IN: userId and UserRoleId != null]) {  
6:        roleIds.put(usr.UserRoleId, usr.Id);  
7:      }  
8:      Map<Id, Set<Id>> parentids = new Map<Id, Set<Id>>();  
9:      for(Id ids : roleIds.keySet()) {  
10:        parentRoleIds.put(ids, getAllParentRoleIds(new Set<ID>{ids}));  
11:      }  
12:      for(Id kys : parentRoleIds.keySet()) {  
13:        for(Id ids : parentRoleIds.get(kys)) {  
14:          if(!parentids.containsKey(ids)) {  
15:            parentids.put(ids, new Set<Id>{kys});    
16:          } else {  
17:            parentids.get(ids).add(kys);  
18:          }  
19:        }  
20:      }  
21:      Map<Id, Set<Id>> mapOfCurrentWithParentUsers = new Map<Id, Set<Id>>();  
22:      // get all of the ids for the users in those roles  
23:      for(User us : [Select Id, Name, Region__c, State__c, UserRole.Name, UserRoleId From User where IsActive = true AND (UserRoleId IN: parentids.keySet() OR UserRoleId IN :roleIds.keySet())]){  
24:        for(Id rids : parentRoleIds.keySet()) {  
25:          if(parentids.containsKey(us.UserRoleId)){  
26:            if(parentids.get(us.UserRoleId).contains(rids)) {  
27:              if(!mapOfCurrentWithParentUsers.containsKey(roleIds.get(rids))) {  
28:                mapOfCurrentWithParentUsers.put(roleIds.get(rids), new Set<Id>{us.id});   
29:              } else {  
30:                mapOfCurrentWithParentUsers.get(roleIds.get(rids)).add(us.Id);  
31:              }  
32:            }  
33:          }  
34:        }  
35:      }  
36:      // return the ids as a set so you can do what you want with them  
37:      return mapOfCurrentWithParentUsers;  
38:    }  
39:    private static Set<Id> getAllParentRoleIds(Set<ID> roleIds) {  
40:      Set<ID> mapOfCurrentWithParentRole = new Set<Id>();  
41:      // get all of the roles underneath the passed roles  
42:      for(UserRole userRole :[select Id, ParentRoleID from UserRole where Id IN :roleIds AND ParentRoleID != null])  
43:        mapOfCurrentWithParentRole.add(userRole.ParentRoleID);  
44:       // go fetch some more rolls!  
45:      if(mapOfCurrentWithParentRole.size() > 0){  
46:        mapOfCurrentWithParentRole.addAll(getAllParentRoleIds(mapOfCurrentWithParentRole));  
47:      }  
48:      return mapOfCurrentWithParentRole;  
49:    }  

Happy Coding!!
