Delta Update Explanation: ABR, ADD, AIM, AIE.....

[Former Member]

Hi,

can someone explain me the details of DELTA UPDATE?

What are the differencies among the 20 methods of delta update in RODELTAM?

There is a document that explains the behaviour of records delta-generated by different methods to:

- Infobject

- DSO/ODS

- Infocubes

Thank you,

Claudio

Hi you can fine the Delta updates in RODELTAM and ROOSOURCE tables.

In these The delta( changed and New Records) are calculated with the Help of Images,. After image, Before Image, Reverse Image, Delete Image, Additive image,.,.etc.

For different objects (date targets) the delta is calculated with the combination of the above images,.. as ABR, AIM ,..AIE etc..

you can find these in RODELTAM table.

Hope this is Clear,.

Regards,

Vishwa.
