Local client copy for delta changes

Hello Support,

We have requirement of copying data(local client copy) of last one month. This is a repetative activity and has to be done once in every month.

For example, in DEV we have 3 clients 200, 210 clients. They make changes in 200 client and these changes has to be reflected in 210 clients. For changing 1 month data we can't perfrom client copy with SAP_ALL.

I have an idea that we can perform local client copy using TDMS 4.0 but can we do delta client copy?

So, my question here is

1. Can we perform client copy for specific seleted data(by date, for eg last 30days) without deleting existing data?

2. We have step 'Start Deletion od Data in Receiving System' in Time Based Reuction scenario, can we skip this and continue proceed with client copy?

Thanks,

Uday.
