Transports 

Purpose

In most cases, Business Information Warehouse development projects are not carried out in a productive system, rather in one or more development systems, depending on their scope.

If your development projects are done in one development system you have to transport the developments to the target system (a test or productive system).

You can use the transport connection to collect newly created or changed Business Information Warehouse objects in the respective development system, and subsequently transport them in using the Change and Transport Organizer (CTO).

Process Flow

The following diagram illustrates the transport process:

A typical system landscape is made up of a development system, a consolidation system and a productive system. You can only transport between either OLTP systems (O1,O2,O3) or between BW systems (B1,B2,B3). Communication between OLTP systems and BW systems takes place using the RFC (Remote Function Call) during uploading.

...

       1.      Extractor enhancements and metadata changes are automatically written to transport requests in OLTP systems. These have to be transported from the OLTP development system into the OLTP consolidation system and for here into the OLTP productive system.

       2.      To be able to transport objects specific to the source system, for example transfer structures, you need to maintain the mapping table in the BW target system. Transfer rules and DataSources are converted during the transport using mapping tables.

For more information about the special features of source-system objects in the Customer Content, see the documentation on Transport and Delivery of Source-System Dependent Objects.

a.       You are on the Administrator Workbench: Transport Connection screen. Choose  Conversion with quick info Conversion of Log. System Name. The View: “Conversion of Source System Names After the Transport” screen appears.

On the Administrator Workbench: Modeling screen, select Tools ®  Conversion of the Logical System Names. The View: “Conversion of Source System Names After the Transport” screen appears.

b.       Conversions that have already been made are displayed in the mapping table: A Original Source System is generally the OLTP development system. The Target Source System is the OLTP system that is connected with the BW target system. Click on New Entries to get to the New Entries: Overview of Added Entries screen. Specify the logical system name you want for the source systems before and after the transport. You can use input help to select a logical system name for the target source system. Or you can create a new value.

       3.      To maintain system consistency, DataSource metadata from the BW development system is not transported into the following BW systems. You must copy DataSource metadata from the respective OLTP system into each BW system again.

Copy the metadata prior to the first transport between BW systems (B1 in B2, B2 in B3) from the connected OLTP system into the corresponding BW target system.

When a transfer structure is transported for example, it cannot be activated unless the corresponding DataSource is already in the target system.

       4.      Servers with a smaller configuration are sufficient as consolidation systems. In this system, the customer can test how the transports affect system functions.

       5.      BW objects are transported as logical objects (TLOGO objects) from a source system into a target system. You can find an overview of transport-relevant metadata object types in Business Information Warehouse at Transport-Relevant Metadata Object Types.

 

You can change objects of a specific object type even in systems set globally to “not changeable”:

                                                  i.       You are on the Administrator Workbench: Transport Connection screen. Choose  Object Changeability. The Changeability of Object Types screen appears (If System Cannot Be Changed).  The system displays all object types that you can set to “changeable”. (This does not include structural objects, for example InfoCubes).

                                                ii.       Double-click on the object type to make it changeable.

                                               iii.       Choose  Continue.

 

Note that these objects are no longer connected to the transport system. For this reason, SAP only recommends this process for productive systems.

       6.      You can choose between the following strategies for the transport:

-         Standard transport system

-         BW transport system

For more information about the advantages of using each of these processes, see Standard- and BW Transport Connections (a Comparison).
