[Extensibility] Make few variables protected in Standard Statement Report (1316)

[shadow747]

Describe the request

Could these variables be made available as protected to be used in report extension logic.

protected var
CustAddr: array[8] of Text[100];
CompanyAddr: array[8] of Text[100];
PeriodLength: DateFormula;

Additional context

These fields are required for extensibility in making addresses usage based on setup configured and periodlength required to handle custom aging bands.
