Addition of 'created by' and 'created on' field in customized table

I have created a Z table with the following fields:

Mandt

Bukrs (Company Code)

Saknr (General Ledger)

Created_by

Created_on

As per the requirement, whenever a new entry is created in the Z table, by default 'created by' and 'created on' field should be populated in the Z table.

For eg.

When I'll do an entry with Bukrs = 7000 and Saknr = 123456 and my table entry should look like

Company_Code General_Ledger Created_by Created_On

7000 123456 John <date-Time>

So how will I get Createdby and createdon field
