When you run Time Evaluation you notice that for some days it has missed the running.
Even though that the Payroll can have a whole different customizing when it comes to periods (e.g. bi-weekly, weekly, monthly), the Time evaluation is recommended to have only one type, which is monthly.
This configuration is coded on table TRMAC, on macro RP-DEF-TIME-PERIOD. And periods for this monthly period, are extracted from PA table T549Q -> record 01 (monthly). An example of this record is below:
If you have made a unusual customizing for the 01 record of V_T549Q, either you restore to the SAP standard, or copy the monthly standard and change on the Macro so that you don't have any issues with this setting on Time Evaluation.
