Hi
In our client also we do monthly depreciation automatic job. Since, dynamic variables are not allowed by RAPOST2000 program, we have used 2 TVARVC's - one for period and one for year and used them in the variant with "T" in the selection variable.
Please note that the TVARVC's need to be updated monthly and yearly respectively before the depreciation run job so that the job runs for the correct period and year.
Regards
Sowmya
