User dependent defaut values in IW48

Hi Experts,

We would like to display posting date as user defined default value in IW48. When we select orders in IW48, current date is captured automatically as posting date. We want to replace this date with a different one. How to achieve this?

I tried to create a default variant but once we select All Actual data, this date is getting replaced by current date.

Is there any option to replace posting date with new date. If I copy date and paste it to this column only limited dates are getting copied. How to copy bulk data to this Transaction code?

Regards,

Sibin
