Hi Uday,
In order to copy the data of last few days (say last 1 month), you need to specify the appropriate data slice date (FROM DATE) in the Time based reduction package.
As Sreejith has mentioned, you should not skip the data deletion step. It might cause inconsistencies in the
receiver system. Also, the data transfer execution will run into issues.
In case you have this requirement, you need to raise OSS message in CA-TDM* component. The responsible colleagues will evaluate the requirement and adress it suitably.
Regards,
Rupam
