Diagnosis
Local allowance classes appear in the pay scales you have entered forconversion. According to table T5D5L Local Allowance Classes andCareer Assignment, these local allowance classes are also used inpay scale &1.
Therefore, all local allowance classes must be converted for this payscale. This in turn affects other (possibly unselected) pay scales.
Beispiel
Pay scale T1 uses local allowance class K1
and local allowance class K2;
Pay scale T2 uses local allowance class K2
and local allowance class K3;
Pay scale T3 uses local allowance class K3;
In the report, only pay scale T1 should be entered for conversion.Because local allowance class K2 is being used, pay scale T2 concerningLocal Allowances (T510Q) is converted, as is class K3 andtherefore pay scale T3. If pay scales T2 and T3 are not converted tothe euro on the same key date as pay scale T1, local allowance class K2cannot be used at the same time by pay scale T1 and pay scale T2, andthe customizing has to be corrected.
