Extraction Mode for the InfoSpoke 

Use

An InfoSpoke can extract data in two ways:

...

       1.      Full mode (F): the data corresponding to the selection criteria of the InfoSpoke is transferred from the data source into the respective destination.

       2.      Delta mode (D): records that were added since the last extraction only are transferred in this mode. This is only possible for the source objects InfoCube and DataStore object.

Features

The extraction mode can be switched from full to delta mode at any time. You can only switch from delta to full mode if you have not loaded any delta yet.

Note: with delta extraction into DB tables from DataStore objects or InfoCubes, the indicator Technical Key should be set. See also Extraction to Database Tables.

Delta Administration:

Delta Administration displays the requests available in the open hub data source as well as information about whether they have already been read or whether the open hub destination has not yet received them. If that is the case, the requests can be found under the category Requests Not Yet Read. Delta administration offers you the following functions:

·        You can deactivate delta administration. An additional delta request is subsequently not possible. At the same time, the status of all source requests that have already been read is reset to Not Yet Read.

Delta administration is also deactivated if one of the following events occurs:

§         A request that has already been extracted is deleted in the open hub data source.

§         A request that has not yet been extracted is compressed in the open hub data source (InfoCube).

·        You can reactivate delta administration. A delta request is then possible again.

·        In the context menu, you can choose Delete Requests. The request is deleted from delta administration and can be requested again (repeat). You may want to do this if a request does not arrive correctly in the target system.
