Diagnosis
A different characteristic or profile has been used already for time-splitting.

System Response
One and the same characteristic and profile have to be used for time-splitting the various time-characterisitcs, otherwise the system doesnot know how to combine the different results.
If, for example, 0CALQUARTER is split into 0CALWEEK, and 0CALYEAR issplit into 0CALMONTH, and 0CALQUARTER has the value '1.2000', and0CALYEAR '1999' it is not clear how the resulting value for 0CALWEEK(01.2000, 02.2000....) is to be merged with the value from 0CALMONTH(01.1999, 02.1999...)

Procedure
Use the same source characteristic and profile for the time-split asyou do with other characteristics.
