Enahancemnt of COPA Ds

Hi,

I need to include Transportation Zone in COPA data Source.

The Abapers has appended the structure & that feild is availbale in the COPA data source.

But last time when i enhanced the COPA Data source , I deleted & recreated the DS with the same name & checked the newly added value feild in KEB0 Tcode.

But now the Transportation Zone i can directly see in the Data source.But if i check the same feild in KEB0 in display mode i cnat see that feild.

Just getting confused , as i know we cant enhance the Data Source directly, but how come the feilds from the append structure got included in the Data Source.

Regards,

Anita
