calendar - synthetic key issue

HI

I derived a calendar as follows

Calendar: DECLARE FIELD DEFINITION TAGGED '$date'
Parameters first_month_of_year = 1,
fiscal_first_month_of_year = 4

Fields

    Year($1) As Year Tagged '$year',
    
    if( Month($1)>=4, Year($1), Year($1) -1) as FiscalYear Tagged '$fiscalyear', 
    
    Month($1) as Month Tagged '$month',
    
    if( Month($1)>=4, Month($1)-3,Month($1)+9) as FiscalMonthNumber Tagged '$FiscalMonthNumber',
    
    Date($1) as Date Tagged ('$date', '$day'),

    Week($1) as Week Tagged '$week',

    Weekday($1) as Weekday Tagged '$weekday',

    'Q' & Ceil(Month($1)/3)  as FinancialQuarter Tagged '$FinancialQuarter';
    

   DERIVE FIELDS FROM FIELDS [OrderDate] USING Calendar;

table one contains OrderDate

table two contains ProcessDate as OrderDate

I have two tables that needs to link to this calendar but its causing a synthetic key.

is there a way around it?

Kind Regards
