How to have an settings value in a numerator?

Hi Mariya ! Sorry for my bad english.

This is how to get a setting value from the code:

if (SettingsAccessor.Instance == null) return;
this.InvoicePrefix = ((IModelNorthwindSettings)SettingsAccessor.Instance.ObjectSpace.AppSettings().Root()).Documents.Invoice.Prefix.Value;

And my question is how to use the SettingsAccessor value in a Business Numerators?

I would like to have: Invoice.Prefix.Value_{0:,0000}

Example: CTL00001

I hope I was more explicit...

Regards, GB

Hi ! I found another way around my difficulty...

SOLUTION:

public override void AfterConstruction()
{
base.AfterConstruction();

if (SettingsAccessor.Instance == null || ((InheritedUser) SecuritySystem.CurrentUser).Site == null) return;
this.Site = Session.GetObjectByKey(((InheritedUser)SecuritySystem.CurrentUser).Site.Oid);
var prefix = ((IModelAppSettings) SettingsAccessor.Instance.ObjectSpace.AppSettings().Root()) .Billing.InvoicePrefix.Value;
this.NumberPart = $"{prefix}{Site.Code}{DateTime.Now:yy}{DateTime.Now:MM}";
}

[Browsable(false)]
[NonPersistent]
public string NumberPart
{
get => GetPropertyValue("NumberPart");
set => SetPropertyValue("NumberPart", value);
}

And then appy this template: {0:NumberPart}{0:,000000}
