External Data Transfer 

Purpose

You use this component when you want to transfer data from an old/legacy system into the R/3 system using a direct input procedure.

This function is used in the following components:

Features

The data is read and converted from a sequential input file, which you have created using data from your old/legacy system. Before being saved in the R/3 datapool, the data is put through several checks. In the case of an error(s), you can rectify the situation using the error log and additional functions.

To assist you with large masses of data, there is a function with which you can split the input file into several smaller files which can then be transferred at the same time.

In several components there are example programs which you can use as templates for your own program. You can then use an RFC to transfer date from a legacy system in "near time".

For testing purposes, you can create an input file using the test data editor.

Constraints

Selecting data in the source system and creating a sequential input file is not done in the R/3 system.

You can only transfer data which have SAP interfaces in R/3. You can find further information under Transfer Categories in the IMG of the relevant component. Note that there are no transfer categories for some components (CO-PA, for example).
