'Iterate over multiple list in java

While i am trying to convert below code snippet using java8 getting "Local variable sId defined in an enclosing scope must be final or effectively final" error.

Existing code:

String sId = "";
String uId = "";
FinalResp resp = new FinalResp();
List<LiqResp> liqRespList = getResp.getLiqRespList();
for(LiqResp liqResp : liqRespList){
  List<ListOfAcq> listAcq = liqResp.getLiqList(); 
     for(ListOfAcq acqList : listAcq){
        List<Acq> acqs = acqList.getAcqList();
        for(Acq acq :acqs){
         if(sId.equalIgnoreCase(acq.getId()) || uId.equalIgnoreCase(acq.getId())){
           resp.setId(acqList.getId());
          }
       }
   }
}
return resp;

Below is the snippet which i tried to convert using java8:

String sId = "";
String uId = "";
FinalResp resp = new FinalResp();
List<LiqResp> liqRespList = getResp.getLiqRespList();
liqRespList.parallelStream.forEach(liqResp -> liqResp.getLiqList().parallelStream.
forEach(acqList->acqList.getAcqList().stream.map(acq -> {
return conversion(acq, acqList, sId,uId,resp); //getting error here as "Local variable sId 
                                           //defined in an enclosing scope must be final 
                                           // or effectively final"
})));

private FinalResp conversion(Acq acq, ListOfAcq acqList, String sId,String uId,FinalResp resp){
   if(sId.equalIgnoreCase(acq.getId()) || uId.equalIgnoreCase(acq.getId())){  
           resp.setId(acqList.getId());
          }
   return resp;
}

Performance wise is this correct approach.thanks in advance for help.
