!!!CUSTOM WAGE RATE (System Preference)
Initiates custom wage rate logic in the application. Once all of the appropriate [Pay Components|PAY COMPONENTS] are marked as '~[X] Custom Rate',  then the actual program name to invoke the custom logic must be specified in the value for this site preference.

This preference is set by site ([IMST])

The custom wage rate logic identified in this scenario must be defined in as a function in the database which takes no parameters and returns a boolean TRUE;

This data base function has access to all the P2K_PPGENR8 package variables including complete table structures like [Pay headers|P2K_PR_PAY_HEADERS] (K_PPH), [Pay lines|P2K_PR_PAY_LINES] (K_PPL) and [Pay line details|P2K_PR_PAY_LINE_DETAILS] (K_PPLD).  The output of the custom wage rate function is populated into package variables that are then used in the subsequent payroll calculation:
;P2K_PPGENR8.K_CUSTOM_WAGE_RATE:The result of the computation or manipulation.  This is the new wage rate that will be used for that transaction, on the pay line detail.
;P2K_PPGENR8.K_WAGE_MESSAGE: Any diagnostic or informational messaging is populated here.  This ends up in the pay line's [AUDIT_TEXT] field

Care should be taken to ensure that there are no places where the function can abort due to data problems.  This is usually done with a construct at the end like
{{{
EXCEPTION
  WHEN OTHERS THEN
       p2k_ppgenr8.k_wage_message  := p2k_pmgen.error_stack;
       p2k_ppgenr8.k_wage_output   := 0;
  RETURN TRUE;
END;
}}}
