We are working on the SAP R/3 4.6 C and the CRM 4.0 scenario.
We have added some Z fields in the BP transaction through EEWB.
Now i need to replicate the data in these Z fileds to be delta downloaded to the customer master in R/3.
Should i add the z fileds to KNA1 table or i should add the fields in the Screens of Customer Master(XD01).
I am refering to the doc for the Object extension in 3.0.
Thanks in advance.
