• PS_SYSTEM_EXPORT

In each function module there is the parameter OBJECT_METHOD with which you specify the actions, so-called object methods, for example, Read, Create, Update, or Delete to be performed on network objects such as activities or relationships. For example, the object method Read is used to export data from the R/3 System. Some of these object methods require you to specify the individual fields which are called "attributes". The attributes for the network objects are exchanged using either ATTRIBUTE_LINES or ATTRIBUTES . The table field REFNUMBER links the object methods in OBJECT_METHOD with the attributes in either ATTRIBUTE_LINES or ATTRIBUTES.

When you perform object methods, the function modules issue success or error messages to a message log.

This function module allows you to export data out of the R/3 System using the method Read. You specify the range of objects to be read in SELECT_PARAMETERS .

In R/3 Release 3.1G PS_SYSTEM_EXPORT always reads the data from the database and not from temporary buffers.

To import data to the R/3 System you use the object methods Create or Update. All objects that you want to create cannot already exist in the R/3 System, whereas all objects that you want to update must already exist. In contrast to PS_SYSTEM_EXPORT , you do not have to specify a range of objects, therefore there is no table for selecting parameters.

All modifications of the R/3 System are temporary until you perform object method PsSystem.Save. Once you have performed PsSystem.Save, you must log off and log back on to the R/3 System to perform further object methods.
