TDMS - BPL - Reduction criteria with company code and time

Dear All,

I'm trying to make a BPL scenario, with BC_Purchase Order.

As recommanded by SAP, we have restricted to 5 000 objects per scenario.

I need to make a time slice reduction with table AEDAT, and also i would like to take only three company code.

How can i select three company code?

When i record my variant, i just have "Low Value" and "High Value".

May i use one variant by company code?

Or the selection of my company code has to be done earlier.

Regards,

Benjamin
