LIS Extraction is Based on Information Structure.
Create Field Catalogs – (MC18) “Similar to Info Object Catalog.
Create Information Structure – (MC21) “Similar to info Cube”.
Set up the Update Rules – (MC24) “Similar to Update rules”.
Goto T-code “LBW0’.
Give the Information Structure Name
See the Present Setting for the Information Structure
( IF Datasource is not generated )Generating the Data Source
Deactivating the Delta Update – “LBW1”
Do the changes to the updating and Save it
Running the Statistical setup to fill
the data into Information Structure
Goto “SBIW” and follow the path
Version Maintenance :
Normally it is “000” version So load the data to version “&(A” and copy the data from this version to “000”
Date of Termination :
Date of termination to be in past
Click on Execute
We can cross check using “RSA3”
Copy the data from the version “&(A” to “000” using “LBW2”
Using “RSA6” transport the Data Source
Replicate the Data Source in SAP BW and Assign it to Info source and Activate
In SAP R/3 Goto “LBW1” and set the updating to “No Updating and Save
Go Back to SAP BW and Create the Infopackage and run the Initial Load
Once the “Initial delta” is successful before running “delta” load we need to enable delta updating in SAP R/3
Once the Delta is activated in SAP R/3 we can start running “Delta” loads in SAP BW.
LO Extraction
First Activate the Data Source from the Business Content using “LBWE”
For Customizing the Extract Structure – “LBWE”
Maintaining the Extract Structure
Generating the Data Source
Once the Data Source is generated do necessary setting for
Selection
Hide
Inversion
Field Only Know in Exit
And the save the Data Source
Activate the Data Source
Using “RSA6” transport the Data Source
Replicate the Data Source in SAP BW and Assign it to Info source and Activate
Running the Statistical setup to fill
the data into Set Up Tables
Goto “SBIW” and follow the path
We can cross check using “RSA3”
Go Back to SAP BW and Create the Infopackage and run the Initial Load.
Once the “Initial delta” is successful before running “delta” load we need to set up “V3 Job” in SAP R/3 using “LBWE”.
Once the Delta is activated in SAP R/3 we can start running “Delta” loads in SAP BW.
Update Methods
Serialized V3 Update
Direct Update
Queued Delta
Non Serialized V3 Update
Serialized V3 Update:Since the V3 update actually does not recognize the serialized processing of update data, the “Serialized V3 Update” function was created through several corrections in SAP Basis in order to also be able to serialize
The serialized V3 update can only ensure the correct sequence of extraction data for a document if the document is not repeatedly changed within the span of a second.
Furthermore, the serialized V3 update can only ensure the correct sequence of extraction data for a document if the times are permanently and exactly synchronized for all instances in a system. This is because the creation time of the update record, which is determined by the local time for the application server, is used for sorting the update data.
In addition, the serialized V3 update can only ensure the correct sequence of extraction data for a document if it previously had no errors in the V2 update. This is because the V3 update only processes the update data that is successfully processed with the V2 update.
Independently of the serialization, update errors that occur in the V2 update of a transaction and which cannot be reposted have the consequence that the V3 updates for the transaction that are still open can never be processed. This can thus lead to inconsistencies in the data in the BW system.
