ReRun CodeUnit

Rikarddo

I have a codeunit with several functions that calculates a minimum price according to certain costs, and then inserts in the table Sales Line.
I corrected some functions who calculated some costs, is there any way to rerun this codeunit for the current year of 2017 to correct possible errors previously calculated and inserted in the table sales line.
I thought I'd create a report to run the code unit but I do not know how.

Here is the main function with in the codeunit:

GetPVmin(VAR SalesLine : Record "Sales Line";ShipAgent : Code[20];Contacto : Code[20];ShipPostCode : Code[20];Country : Code[10]) : Decimal



SalesLine.SETFILTER(Type,'<>0');

IF SalesLine.FINDSET THEN
BEGIN

IF SalesLine."Document Type"<>SalesLine."Document Type"::Order THEN
  EXIT;

   ltcontact.GET(Contacto);
   IF NOT ltTabDiv.GET('RUBCUSTO',0,'TAXAJURO') THEN
   EXIT;
   ltLocation.GET(SalesLine."Location Code");
   IF ltLocation."Country/Region Code"='' THEN
   ltLocation."Country/Region Code":='PT';
   IF Country='' THEN
    Country:='PT';
   KgTotais:=0;
   distancia:=GetDist(ltLocation."Post Code",ShipPostCode,ltLocation."Country/Region Code",Country);
   REPEAT
     
    IF NOT SalesLine."Item Container" THEN
      KgTotais+=SalesLine.Quantity
    ELSE
    BEGIN
      //Vasilhame:=SalesLine.Quantity;
      ltValueEntry."Entry No.":=SalesLine."Attached to Line No.";
      ltValueEntry."Item No.":=SalesLine."No.";
      ltValueEntry."Valued Quantity":=SalesLine.Quantity;
      ltValueEntry.INSERT;
    END;
   UNTIL SalesLine.NEXT=0;

   SalesLine.SETRANGE("Item Container",FALSE);
   
  

  //roliveira 2017-10-04 begin  
   VVasilhame:=0; 
   IF SalesLine.FINDSET THEN
   REPEAT

     SalesLine.SETRANGE("Item Container");

     QProduto:=0;
     QVasilhame:=0;
     IF SalesLine.FINDFIRST THEN
       BEGIN
         QProduto:=SalesLine2.Quantity;
         QVasilhame:=SalesLine.Quantity;

       END;
         IF QVasilhame<>0 THEN

     SalesLine.GET(SalesLine2."Document Type",SalesLine2."Document No.",SalesLine2."Line No.");
