Today want to give you an idea on how can you customize amount to words transcription in Acumatica.That might be required for any language localization.
Here you can find simple example, but real complexity might be related to your language rules.
All the main work around that feature is done by [PX.Objects.AP.ToWordsAttribute]
It can be defined on virtual field, and upon accessing by UI or Report will do automatic transcription from number to text.
e.ReturnValue = LangEN.ToWords((decimal)((PXDecimalState)DecimalVal).Value, ((PXDecimalState)DecimalVal).Precision);
If you need you can apply that attribute to other amounts and reuse transcription for other reports.
You can read more about it on StackOverflow.
