Transport Connection: Transporting Objects 
In the main menu of the SAP Business Information Warehouse select Administration ® Administrator Workbench.

With the pushbutton Navigation Window On/Off on the application toolbar in the Administrator Workbench you can show and hide the left-hand navigation window.
By choosing the pushbutton Source System Assignment, you can change the selection afterwards and add or remove other source systems from the selection.
If you do not select a source system, all source systems are automatically selected.

The assignment of source systems is only relevant for transfer rules, file DataSources and InfoPackages. If there is more than one source system, then only those objects assigned to the specified source system are transported. Objects that have not been assigned to the specified source systems are ignored.
You can find more detailed information on the respective settings under

Using the function Search for Object, you can also search for objects as a string (for example 0CUST) or pattern (0CUST_*B).
After expanding the tree structure, you can use F4 Help when selecting object types by double clicking on Select Objects. Select the objects here that you would like to transport and transfer them using the pushbutton Transfer Selection.

You can select and transfer more than one object at the same time by multiple selection.
In the column Transport, the objects that have not yet been recorded are selected by default, meaning that they still have the development class $TMP. You can add other objects manually.
Objects being Transported for the First Time (Development Class = $TMP)

This query only comes about once for all collected objects. That is, if you want to transport objects in different development classes, you must collect them together more than once.

You can change the assignment to a development class by selecting an object in the dialog box Collected objects and choosing Change development class from the context menu. Then enter the new development class in the dialog box Change object catalog entry.

First, release the individual tasks and then the complete request.
Objects Already Transported
The first time these objects were transported, a development class was assigned; meaning, these objects have since then been subject to automatic change recording. In this way, all the changed objects are written automatically to a request, and can be transported.

The automatic change recording is only valid for objects that are already assigned to a transportable development class. It can happen that, for example, new InfoObjects are created for an InfoCube, which is subject to automatic change recording. These are not automatically written to the request for the InfoCube, rather they are given the development class $TMP, meaning that these objects, or the InfoCube, have to be collected in the transport connection and transported accordingly.

Only refrain from collecting objects using the transport connection when making changes, meaning in those cases where no new objects are produced.
