Delta update

[Former Member]

Hi friends,

For LOgistic (LO) datasource, there is a delta mechanism provided by RSA7, central delta management. Now if i develop a generic datasource, which que will take care of delta? whats the table which contains the delta?

I want to know how exactly generic delta works. How to design the generic delta datasource and the mechanism to identify delta.

Regards

Sriram

Hi,

For detail info about generic datasource & delta please see:

If you have any quesions left: please ask.

If you are satisfied: please say thanks by rewards.

there r 3 ways by which a delta is being handled when u create a generic ds. it can be on 0calday, numeric pointer and, timestamp.

Hi Sriram!

I think you can look here to better understand what you need...

Hope it helps!

thnx zep,

I know how RSA7( The delta for LO )works.. but i'm not very sure how the delta works for generic data sources. If the data source is delta enabled, what r the tables associated with that etc etc. If any document, that will be great.

Sriram,

I'll try my hand at explaining..

Delta is not something that is proivided by RSA7.Delta is an attribute (if I can call it!!) of your data source, your data src has to be capable of handling delta. i.e it has to be handled in the code as to how it is extracting etc.Table ROOSOURCE has information as to If your datasrc is delta enabled or not.

RSA7 data you see is what data is ready for the next delta load.

Hence if you are writing your own custom datasrc , you need to handle the delta mechanism.

There are lot of threads here on SDN as well as ITTOOLBOX as to how to write a generic data src.

Best Luck.
