Time Slice for ECC6.0 EHP6 used mainly for IS-UT and FI-CA

Hi,

We are planning to create a test system using TDMS Shell creation -- Followed by Time slice data transfer -from our existing copy of production system ECC6.0 with EhP6. Although the current production system is only used for FI-CA andIS-UT(Telecom related processes). There is not much or even say 0 data for SD and MM related tablesin thesystem.So my questions are: -

1) Should I use Standard Time ReductionPackagefor SAP  ERP for Data transfer after shell creation or Is there any other option available by which I can transfer required data.

   Since the system is only used for FI-CA andIS-UT functionality mainly. The tables which usually takesa lot of time during data selectionare emptylike EQUI,JEST,VBUK ,STXH  etc

2) The system has large. Z-tables and we do not want to tranfer them in full , I have read in previous posts of option specify reduction rule but When I tried for previous TDMS systems it does not worked , So any specific steps for the same so as to cross check where I went wrong.

Regards,

Umesh
