Transport System 

Purpose

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

If you carry out your development projects in a development system, then you must transport the developments into the target system (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 connection with the Change and Transport Organizer (CTO).

You can find additional information about the SAP Change and Transport System (CTS) in the Basis documentation under

Process

The following diagram illustrates the transport process:

A typical system landscape consists 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. Make sure that the Customizing and metadata settings agree with each other in the development and productive systems. 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. In order 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. During transport, InfoSources assigned to a source system are converted using the map table.
    1. You are on the Administrator Workbench: Transport Request screen and have selected InfoProvider in the left navigation window. Choose Conversion with the Quick info Logical System Name Conversion. The screen View "Source System Name Conversion After Transport" appears.

      2. On the Administrator Workbench: Modeling screen, select Tools -> Logical System Name Conversion. You then reach the View "Source System Name Conversion After Transport" screen.

    2. Conversions that have already been made are displayed in the mapping table: A Primary Source System is generally the OLTP development system. The respective Target Source System is the OLTP system connected with the BW target system. You access the New Entries: Added Entries Overview screen via New Entries. Specify the logical system name you want for the source systems before and after the transport. You can use value help to create a new value or select a logical system name for the target source system.
  1. To maintain system consistency, DataSource metadata from the BW development system is however not transported into the following BW systems. You must replicate DataSource metadata from the respective OLTP system into each BW system again.

Replicate 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 can only be activated when the corresponding DataSource has already been made available in the target system.

  1. Servers with a smaller configuration will suffice for the consolidation systems. In this system, the customer can test how the transports affect system functions. Make sure that the customizing and metadata settings are in agreement in the consolidation and productive systems.
  1. BW objects are transported as logical objects (TLOGO objects) from a source system into a target system. An overview of transport-relevant metadata Object types in Business Information Warehouse can be found under Transport-Relevant Metadata Object Types.

 

You have the following option to change objects of a specific Object type even in systems set globally to "not changeable":

      1. You are on the Administrator Workbench: Transport Connection screen. Choose Object Change Option. You reach the dialog window Change Option For Object Types (If System Cannot Be Changed). The system displays all Object types that you can set to "can be changed". (This does not include structural objects, for example InfoCubes).
      2. Double-click on the Object type to change it.
      3. Choose Next.

 

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

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

You can find additional information about the advantages of using each of these processes under Standard- and BW Transport Connections (A Comparison).
