How to fix this error?

The customising table T5GPBS28 allows standard (or customer specific)
Time Units to be selected (from T538A) and made available for use in
any or all of the following three places;
1) Rollback Period Time Units - Customising Start Rules (T5GPBS21)
The Standard Time Units available as delivered are 'R10', 'R12' and
'R13', which are Rollback Period Time Units of calendar Days, Months
and Years respectively.
2) Entitlement Amount Time Units - Customising Scheme Rules (T5GPBS23)
The Standard Time Units available as delivered are 'E10' and 'E11',
which are Entitlement Amount Time Units of Entitlement Days and
Entitlement Weeks repectively.
The definition of a Entitlement Day, is simply whether or not the
employee works on a day or not, will imply whether the employee
recieves their entitlement on that day or not.
The definition of a Entitlement Week, is a little less robust. For
Non-shift workers (i.e. with a single weekly rotating working pattern
or personnel work schedule with ONLY one weekly work schedule) this
will imply that they will recieve the number of working days in a
normal week as the number of entitlement days in an entitlement
week.
3) Multiplier Time Units - Customising Time Unit Multipliers (T5GPBS24)
The Standard Time Units available as delivered are '001', '010',
'011', '012', '013', which are Hours, Days, Weeks, Months and Years
respectively. EACH of these MUST been further defined using a
multiplier. This multiplier will allow the standard Absence
Evaluation processing to decide how many days are in the Time Unit.
In this way the Time Unit can be used for either Rollback Periods or
Entitlement Amounts.
