SAP-BI@Open Hub Service ( Info Spokes )

Open Hub Service ( Info Spokes ):-
----------------------------------
* Retraction.
* Retracting the Data back from BW ( Info Cubes, ODS, MD - ATTR,TEXT,HIER) into Flat Files or Data base tables.
* Scenerio(1)  - Management Cockpit
* How to create Info Spokes to Retract data from Info Cube to Flat file?
* When we Retract data with the Infospokes it creates to files ( Data file and Header file (s_xxxxxxxx))
* Both the Flat files would be .CSV files.
* When retracting the Data the Infospokes are Aggregating the records based on the Characteristic values.
* NAMEING CONVENTION OF THE TABLE - /BIC/OHxxxxxx(DESTYINATION NAME ).
* Delta Mechanism for Info Spokes.
* Scenerio(2) - Loading from Info Cube to Info Cube based on a Request.
* Transformations Using BADIs's.
In the Infospoke screnn - Transformation Tab - Select the Chek box "Info Spoke with transformations using BADI's" then it automatically creates an Implementation class with the naming convention as 'ZCL_IM_xxxxxxxx' ( SE24 ) and with an interface 'IF_OPEN_HUB_TRANSFORM' and this interface brings in the method 'IF_OPEN_HUB_TRANSFORM' and then we start writing the transformation code in this method.
* loop at E_T_DATA.
if E_T_DATA-salval = 0 and E_T_DATA-salkg = 0.
delete E_T_data.
endif.
* Limitation of Info Spoke:-
--------------------------
* Using Info Spoke we cannot retrive the data if it is available in multiple data Targets.
* Info Spoke will not work for Virtual Providers.
