Posting Date is set to Accruable Start Date, even though the accrual rule is defined to set posting date is equal to Accruable End Date.
Reproducing the Issue
In a Time Account Type,
1. Set Account Booking Offset [Months] to zero in Time Account Type
2. Set posting date as Accruable End Date in accrual rule of the Time Account Type(as shown in the picture).
The posting date defines the date on which the accrual is available for the employee.
The posting date must fall within the bookable period of the time account.
If we are giving a date beyond the bookable period system will take Accruable Start Date as posting date.
