Data Warehouse InfoObjects can be defined as the data elements to populate the Data Warehouse layer of your Enterprise Data Warehouse. Please refer for a conceptual overview to my blog Introducing Data Warehouse InfoObjects - Part 1: Conceptual Overview. For SAP source systems it is advisable to take advantage of the structured and comprehensive ABAP Data Dictionary to generate these Data Warehouse InfoObjects. Please refer for more technical details to my blog Introducing Data Warehouse InfoObjects - Part 2: Technical Details.

I created an ABAP program to generate Data Warehouse InfoObjects for SAP source systems’ DataSources. For more information on using the program please refer to the blog series:

Generating Data Warehouse InfoObjects - Part 1: Introduction;

Generating Data Warehouse InfoObjects - Part 2: Metadata Repository;

Generating Data Warehouse InfoObjects - Part 3: Customizing;

Generating Data Warehouse InfoObjects - Part 4: Optimizing Results.

I would like to share via 3 documents detailed technical instructions how to create the ABAP program and all related objects. Implementing Data Warehouse InfoObjects - Part 1: ABAP Dictionary Objects explains how to create all ABAP Dictionary objects. Implementing Data Warehouse InfoObjects - Part 2: ABAP Programming & Other Objects focuses on ABAP programming and other ABAP Workbench objects. Part 3 describes all ABAP developments to be done in every SAP source system that is subject to Generating Data Warehouse InfoObjects.
