LO Steps:
Go to LBWE and maintain the data source.
Make sure all users are locked in the system.
Go to LBWG and delte the setup table.
Delete the delta queue from RSA7
Go to transaction code SBIW and start the filling of setup table.
Replicate the data source BI side.
After completion of setup table from R/3 side you can fetch the data by infopackage
Update types:
Queued Delta
Direct Delta
Unserialized V3
Queued Delta: With queued delta update mode, the extraction data (for the relevant application) is written in an extraction queue (instead of in the update data as in V3) and can be transferred
to the BW delta queues by an update collective run, as previously executed during the V3 update.
After activating this method, up to 10000 document delta/changes to one LUW are cumulated per datasource in the BW delta queues.
Direct Delta: With this update mode,Each document posting is directly transferred into the BW delta queue
Each document posting with delta extraction leads to exactly one LUW in the respective BW delta queues
Just to remember that ‘LUW’ stands for Logical Unit of Work and it can be considered as an inseparable sequence of database operations that ends with a database commit (or a roll-back if an
error occurs).
Unserialized V3: With this update mode, that we can consider as the serializer’s brother, the extraction data continues to be written to the update tables using a V3 update module and then is
read and processed by a collective update run (through LBWE).
But, as the name of this method suggests, the V3 unserialized delta disowns the main characteristic of his brother: data is read in the update collective run without taking the sequence into
account and then transferred to the BW delta queues.
Setuptables: Access to application tables are not permitted, hence setup tables are there to collect the required data from the application tables.When a load fails, you can re-run the load to pull
the data from setup tables. Data will be there in setup tables. Setup tables are used to Initialize delta loads and for full load. Its part of LO Extraction scenario.
