How to identify missing records in source with help of DSO?

[gregor_kolck]

Hi Experts,

I want to use a DSO to generate Delta with changed or new records. So far o.k.

Additionally I want to have "delete records" in delta with records missing or deleted in the source.

Example:

1st Request

Load from Source
CHAR
A
B

Changelog / Delta
CHAR 0RECORDMODE
A    N
B    N

2nd Request

CHAR
A
C

No I want produce a delta that indicates C is new and B is deleted, something like

Changelog / Delta
CHAR 0RECORDMODE
C    N
B    R

Any Ideas?

Best regards

Gregor
