Portal Commission Sharing with Multiple Reps

Question

Currently with this trigger I created, if a portal user creates a commission split it will be shared with the group that the portal user is in. Recently they told me that it needs to be shared with multiple other users so they can go through the approval process. Is there anyway I can edit my current trigger to do this?

 Map<id,User>PartnerUsermap = new Map<id,User>([select id,UserType from user where  UserType = 'PowerPartner' and isActive = true] );     
List<GroupMember>GroupMemberList = new List<GroupMember>([select GroupId,UserOrGroupId from GroupMember]); 

List<Split__Share> CsShareList = new list<Split__Share>();

if(!PartnerUsermap.isEmpty()){
     for(Split__c cs : trigger.new){  
            if(PartnerUsermap.containsKey(cs.CreatedById)){
                for(GroupMember grpmem : GroupMemberList){
                    if(grpmem.UserOrGroupId == cs.CreatedById){   
                        Split__Share  csshare = new Split__Share (ParentId = cs.id,UserOrGroupId = grpmem.GroupId,AccessLevel = 'Edit');                          
                        CsShareList.add(csshare);                           
                    } 
                }

I need to add the following Reps to the sharing logic.. I'm having a hard time figuring out the logic and process. Does anyone have any insight?

Answer 1

The key to doing what you desire will be in how you query the user map you're using to create the splits. If the additional reps are always the same, or known based on certain criteria, they can be added to your initial queried map using standard map methods. That would presumably allow you to salvage most of your existing code.
