Will anybody please explain me the functionality in the following link :
What i want to know is that under the heading :
Case 1: Copy sold-to party field (KNA1) -> sales document header (VBAK)
*The field exists in KNA1 and can be copied to the sold-to party view KUAGV and to VBAK. The name is the same. *
The field does not exist in KNA1 or VBAK. You must create it there. Note that new data elements and new field names must begin with the letters "ZZ". The names are not the same.
Here there is a reference of names to be identical.Can anybody explain me the the names it is referring to.Since based on this there is a different methods to be followed.
Points will be rewarded
Thanks in advance
