Change BI when Add field of COPA table in ECC

Hi all.

I'd like to add new field of copa table(CE1XXXX).

Now, COPA is connected with BI Cube with delta mode.

Should I recreate new datasource for new field and use init mode When I create new field of CE1XXXX table?

I don't want to break delta mode in current infopackage.

Is there any way to solve it?

Thanks.
