General Transport Description (SAP Library - Human Resources Information System)

General Transport Description

Queries, InfoSets and standard area user groups are usually stored in the client-specific table AQLDB. When transporting these objects, however, you use the transport table AQTDB, which is not client-specific.

You can transport objects either

from one client (the source client) to another client (the target client) within the same SAP System

from one client (the source client) in one R/3 System (the source system) to another client (the target client) in another R/3 System (the target system).

In both cases, you use similar procedures. For a graphical overview, see Transporting Query Objects.

There are two options for performing transports. The first of these involves using the transport table AQTDB and the transport actions Export and Import.

You must first export the objects for transport from the table AQLDB to the transport table AQTDB.

This creates a transport request for the transport system that includes all entries created by the export from table AQTDB (transport dataset). The request covers all the entries from table AQTDB (transport dataset) generated by the export and has a name which corresponds to transport system conventions (sysKnnnnnn).

The name of the transport request is given in the export log.

In the table AQTDB, the transport dataset is stored under a key which matches the name of the transport request.

If you are transporting within one R/3 System (that is only from one client to another), you can also import the transport dataset from the target client.

In this case, you use the name of the transport request which is specified during the export and matches the key of the transport dataset in the table AQTDB.

During this import, the system reads the transport dataset from the transport table AQTDB into the table AQLDB. At the same time, it performs numerous checks which ensure that no inconsistencies occur in the table AQLDB.

Note

Both export and import are functions of the SAP Query transport tool.

If you are transporting from one R/3 System to another, you must use the transport system to release and export the transport request created by the export.

This procedure transfers the transport dataset from the transport table AQTDB of the source system to the transport table AQTDB of the target system. Then, you can perform an import from the target client of the target system, as described above.

Note

The transport datasets created in the transport table AQTDB by exports are not deleted after successful imports unless you specify this explicitly beforehand. For this reason, you cannot import a transport dataset several times, for example to transport an InfoSet to several clients.

The second transport option involves transferring files via the R/3 download/upload interface. To do this, you use the transport functions Download and Upload.

You must first download the source client objects for transport from the table AQLDB to a file. When doing this, you specify the file name and exactly where it is stored in the file system. A file can only contain one transport dataset, meaning that any existing file is overwritten. Downloading a transport dataset to a file effectively means that it cannot be read back into the table AQLDB.

Then, you can upload the transport dataset stored in the file. Here, the transport dataset is read and inserted in the table AQLDB. As with an import, the system performs numerous checks which ensure that no inconsistencies occur in the table AQLDB.

After this general overview, you can familiarize yourself more closely with the individual options offered by the transport tool. On the initial screen of the component Maintain InfoSets or Maintain User Groups, select Transports. You then see the following screen:

This graphic is explained in the accompanying text

You must make a number of entries here. First, you choose one of the following transport actions by selecting the appropriate radio button:

Transport action:

Description:

Export

Generates a transport dataset in the table AQTDB

Import

Reads in a transport dataset from the table AQTDB

Download

Generates a transport dataset in a file

Upload

Reads in a transport dataset from a file

Display

Displays the transport dataset in the table AQTDB

Delete

Deletes transport datasets from the table AQTDB

Copy Standard Area ® Global Area

Copies query objects from the standard area to the global area

Copy Global Area ® Standard Area

Copies query objects from the global area to the standard area

When you have specified this field and, if necessary, other fields, you can start the transport action by selecting Execute. The system always generates a log containing details of the individual actions executed.
