Error with developing a report in AL code in Dynamics 365 BC

AitorEG

Hi eveyone,
I don't know if this is the best place to ask this question. I'm developing a new report, and the issue is this.
This is how the datset is defined:

dataset
    {
        dataitem(Item;Item)
        {
           DataItemTableView=SORTING("No.");
           RequestFilterFields = "No.","Inventory Posting Group","Location Filter","Variant Filter" ;
           trigger OnPreDataItem() 
           begin
                Location.SETRANGE("Use As In-Transit",FALSE);

                               DialogWindow.OPEN(Text000 +Text001 +Text002);
                               //BETEASTD SaveFilters := TRUE;
                               SaveFilters := FALSE; //BETEASTD
           end;
           trigger OnAfterGetRecord()
           var
               ItemVariant: Record 5401;
           begin
           IF SaveFilters THEN BEGIN
                                    LocationFilter := GETFILTER("Location Filter");
                                    VariantFilter := GETFILTER("Variant Filter");
                                    SaveFilters := FALSE;
                                  END;
                                  SETFILTER("Location Filter",LocationFilter);
                                  SETFILTER("Variant Filter",VariantFilter);
                                  Location.SETFILTER(Code,GETFILTER("Location Filter"));

                                  IF ReplacePreviousSKUs THEN BEGIN
                                    StockkeepingUnit.RESET;
                                    StockkeepingUnit.SETRANGE("Item No.","No.");
                                    IF GETFILTER("Variant Filter") <> '' THEN
                                      StockkeepingUnit.SETFILTER("Variant Code",GETFILTER("Variant Filter"));
                                    IF GETFILTER("Location Filter") <> '' THEN
                                      StockkeepingUnit.SETFILTER("Location Code",GETFILTER("Location Filter"));
                                    StockkeepingUnit.DELETEALL;
                                  END;

                                  DialogWindow.UPDATE(1,"No.");
                                  ItemVariant.SETRANGE("Item No.","No.");
                                  ItemVariant.SETFILTER(Code,GETFILTER("Variant Filter"));
                                  CASE TRUE OF

           end;

        }
    }

As you an see, I have 3 calls to the "CreateSKU" procedure, and I have this error:



I've defined the procedure inside the requestPage like this:



But it seems I should define it in other place. Any hint?

Thank you very much
