Editing Transfer Files with the Editor 
You can use the data transfer editor to modify a data transfer file. This editor is particularly useful if you want to edit transfer data during the test, that is, before it is actually transferred. In a converted file, you can correct errors, for example.
An initial data transfer file or a different file in the appropriate format is available.
You can edit the transfer file at field or structure level. In particular, you can:
Delete structure lines
Duplicate structure lines
Edit blocks of structures (that is, select, cut or copy, and paste)
Edit fields in individual structures by entering field values
The possible entries in the editor are usually supported by the input help.
In the Data Transfer Workbench, choose . The Data Transfer - Tools screen appears.
Choose an existing transfer file for an object type and the associated task type, program type, and program/method, and choose Change File.
