CONFIDENTIAL
*) The first Data Source (2LIS_03_BX) is used to extract an
opening stock balance on a detailed level.
*) The second Data Source (2LIS_03_BF) is used to extract the
material movements into the BW system. This Data Source provides
the data as material documents.
*) The third Data Sources (2LIS_03_UM) contains data from
valuated revaluations in Financial Accounting.
Data Sources in R/3
-
CONFIDENTIAL
Upload sequence and compression
-
CONFIDENTIAL
Initialization of the current stock (opening balance) in the R/3
source system with Data Source 2LIS_03_BX (transaction code in R/3:
MCNB).
STEP 1
-
CONFIDENTIAL
Activate the extract structure MC03BF0 for the corresponding
Data Sources 2LIS_03_BX/2LIS_03_BF in the LO cockpit (transaction
code in R/3: LBWE) before
initializing the opening balance.
-
CONFIDENTIAL
STEP 2 Setup of statistical data for material documents in the
R/3 source system.
-
CONFIDENTIAL
Current stock balance with Data Source 2LIS_03_BX in the setup
table MC03BX0SETUP.
Historical material documents with Data Source 2LIS_03_BF in the
setup table MC03BF0SETUP belonging to extract structure
MC03BF0.
Postings done after the set up are found in the extraction queue
or central update table (VBDATA). They can be later transferred
into the BW using the delta queue.
-
CONFIDENTIAL
After executing the menu entry, a dialog box appears in which
you must specify whether you want to carry out a setup for material
movements (2LIS_03_BF) or for revaluations (2LIS_03_UM).
-
CONFIDENTIAL
Loading the opening stock balance (Info Source 2LIS_03_BX) into
Info Cube 0IC_C03. In the Info Package, choose the upload mode
Create opening balance
STEP 3
-
CONFIDENTIAL
Compressing the request containing the opening stock that was
just uploaded. Make sure the "No marker update" indicator is not
set.
STEP 4 & 5
Loading the historical movements into the Info cube 0IC-C03 via
the Data Source/ Info Source 2LIS_03_BF. Choose the upload node
Initializing the delta process here.
-
CONFIDENTIAL
After successfully uploading the historical material movements,
the associated request has to be compressed. You must make sure the
"No marker update" indicator is set. This is necessary because the
historical material movements are already contained in the opening
stock.
STEP 6
-
CONFIDENTIAL
Initializing the Data Source, where data is written from the
extraction queue or central update table into the delta queue.
STEP 7
-
CONFIDENTIAL
After executing the menu entry, the LO cockpit appears
(transaction is LBWE): Here, you can manually start the run for the
different applications, or schedule it periodically.
-
CONFIDENTIAL
NOTES:
The request in which the opening stock was loaded must always be
compressed with a marker update
The request in which the historical material documents were
contained must always be compressed without a marker update and
Successive delta uploads must always be compressed with marker
updates.
You do not need to initialize the stock. If you do not
initialize, the system assumes a zero opening stock balance.
You can also model a stock scenario partially or completely
using flat files. This allows you to define a flat file Data Source
as an "opening balance".
Dont update Info Cube 0IC_C03 from an ODS layer. Update the Info
Cube and the ODS layer in parallel from the PSA layer.
Successive (for example, daily) delta uploads can be started
with the Data Source 2LIS_03_BF from this point in time on. These
requests should also be compressed after successful validation. You
need to use a marker update with this compression.

Current date: 31.03.2002
You have set up an opening balance of 100 units on 01.01.2002
and loaded it into the stock Info Cube.
Historical material movements from the three previous months
(October 2001:10 units; November 2001: 20 units; December 2001: 10
units) are loaded into the BW.
Delta requests transferred at the end of January (20 units) and
February (10 units) were already compressed after successful
validation.
The last delta request from the end of March (10 units) is still
in the Info Cube in uncompressed form.

VALIDITY TABLE
-
CONFIDENTIAL
For Info Cubes with non-cumulative key figures, you need to
maintain a validity table when creating the Info Cube. This table
specifies the time interval for which the non-cumulative are valid
for a specific characteristic combination.
