在Acumatica 21R1中，当在报表中使用冻结过滤器时，由于平移行为的不当，可能会导致冻结过滤器失效，导致报表无法正常显示。

以下是一个示例报表，其中使用了冻结过滤器：

public class ARTotalByPeriodEnq : PXGraph { ... public PXFilter Filter; ... public PXSelect ARBalances;

public ARTotalByPeriodEnq()
{
    ...
    this.Filter.Cache.AllowInsert = false;
    ...
}

public PXAction viewDocument;
[PXUIField(DisplayName = Messages.ViewDocument, MapEnableRights = PXCacheRights.Select, MapViewRights = PXCacheRights.Select)]
[PXButton(ImageKey = PX.Web.UI.Sprite.Main.View)]
public virtual IEnumerable ViewDocument(PXAdapter adapter)
{
    if (this.Report.Current != null && ARBalances.Current != null && (!String.IsNullOrEmpty(ARBalances.Current.DocType) && !String.IsNullOrEmpty(ARBalances.Current.RefNbr)))
    {
        switch (ARBalances.Current.DocType)
        {
            case GL.BatchTypeCode.ARInvoice: 
                ...
                break;
            case GL.BatchTypeCode.CreditMemo:
                ...
                break;
            case GL.BatchTypeCode.Payment:
            case GL.BatchTypeCode.Prepayment:
            case GL.BatchTypeCode.Refund:
                ...
                break;
            case GL.BatchTypeCode.Adjustment:
                ...
                break;
            case ARDocType.DebitMemo: 
                ...
                break;
            case ARDocType.CashSale:
            case ARDocType.CashReturn:
                ...
                break;
            default:
                ...
                break;
        }
        return adapter.Get();
    }
    return adapter.Get();
}
...

}

为了解决这个问题，需要在报表中添加以下代码：

public PXSelect ARBalances; public ARTotalByPeriodEnq() { ... this.ARB
