Process Chains: Delta Data Loading (SAP Library

Process Chains: Delta Data Loading

Technical name: 0SD_DLV_DELTA_P01

Purpose

This process chain activates and periodically fills all data targets for the scenario Backorders in Production (display component Process Chains Delivery Service SD (0SD_DLV), InfoArea Delivery Service (0SD_DLV)).

With this process chain, changes made since the last loading process are updated (delta transmission) in the data targets affected.

The data loading processes and the associated activation of ODS objects can be scheduled in one step and monitored centrally in the log view. Individual scheduling and monitoring of InfoPackages does not apply, nor do activation of ODS objects and subsequent further posting in the data targets.

Dependency Between Processes

Step	Process Type	Successor
1	Start process Delta Data Loading	2
2	Load data InfoPackage 2LIS_11_V_SSL_DELTA_R3	If successful, 3
2	Load data InfoPackage 2LIS_11_VAITM_DELTA_R3	If successful, 4 If successful, 5
2	Load data InfoPackage 2LIS_11_VASTH_DELTA_R3	If successful, 10
2	Load data InfoPackage 2LIS_11_VAHDR_DELTA_R3	If successful, 10
3	Activate 0DS data 0SD_O04	If successful, 6
4	AND (and-process for activation 0SD_O01)	If successful, 7
5	Activate 0DS data 0SD_O02	If successful, 8
6	Load data InfoPackage 80SD_O04_FULL_DATAMART	-
7	Activate 0DS data 0SD_O01	If successful, 9
8	Load data InfoPackage 80SD_O02_DELTA_DATAMART	If successful, 10
9	Load data InfoPackage 80SD_O01_DELTA_DATAMART	If successful, 10
10	AND (and-process for activation 0SD_O03)	If successful, 11
11	Activate 0DS data 0SD_O03	If successful, 12
12	Load data InfoPackage 80SD_O03_DELTA_DATAMART	-

This process chain has the following scheduling options:

Delivered scheduling option: planned start: January 2, 2003 – 12:00 a.m.
Variant setting for the start process: direct scheduling

Prerequisites

Beware of the following points during the transfer of the Business Content:

If you are using an SAP source system:

During the transfer, collect the process chain SD_DLV_DELTA_P01 as usual with the necessary objects (or, where applicable, data flow before and/or after).
Beforehand, when assigning the source system, select the affected SAP source system and the SAP BW application component itself.
Transfer the collected objects.

If you are using more than one SAP source system (with identical SAP DataSources):

During the transfer, collect the process chain SD_DLV_DELTA_P01 as usual with the necessary objects (or, where applicable, data flow before and/or after).
Beforehand, when assigning the source system, select the affected SAP source systems and the SAP BW application component itself.
Transfer the collected objects.

Following the transfer of the process chain, the following postprocesses are required:

In the transaction Process Chains (RSPC), select your transferred process chain.
If you selected more than one SAP source system during the transfer, remove the link between the processes of type Load Data, which have InfoPackages with identical InfoSources, and the successors. Then add, for example, the process type AND and toggle this connection between the just-removed link.
Following the start process, several data loading processes from the SAP R/3 system are triggered in parallel. Check whether there are enough processes available in the source system. If necessary, modify the link to a sequential one.
Adjust the scheduling options of your start process to your requirements. To do this, double click on the process type Start.
If required, enhance the process chain with further processes, e.g. the setup of indices or the compression of InfoCubes.
Then save, check and activate the process chain and provide information, where applicable, about which server the process chain should be scheduled on. Then use the function Activate and Schedule to start the process chain according to your scheduling options.

Execute these activities following the successful run and, where applicable, adjustment/enhancement and activation/scheduling of the process chain Initial Data Loading (0SD_DLV_INIT_P01).

This process chain supports SAP R/3 standard systems as of Release 4.0B.
