Updating enhanced structure fields using ALE change pointer mechanism ??

Hi.

If a master data datasource is enhanced with an append and this datasource has 'delta' field set to A, how can I ensure that delta is delivered on the additional fields too ?

An example is,

Datasource : 0COSTCENTER_ATTR

Extract structure : BIW_CSKB

Extractor : BIW_CSKB

Extraction methods : DB View

Delta process : A

If I now add fields - PKZKS,PKZER to the extract structure in an append, how will delta mechanism work ? Please note that these two fields are already available in the DB view BIW_CSKB.

Best regards.
