3449386 - RTC- Consolidations -Cash Flow Job failure with data over flow error.

After upgrade Cash Flow Job run derived abnormal numbers in calculations for 2 days job runs and third day CF Job run failed with Data over flow error.
As per analysis it seems derived data in currency translation is in 30 characters length for specific account. 

Cash Flow is executed after Currency translation and that is the source data. so source data for CF got 30 char length and SAP takes up to 23 Char length, that is why job failed with data over flow error.
ST22 errors
