Using the Test Data Editor 
Use
You use this function to create sequential files and fill them with test data for testing the external data transfer.
Prerequisites
The test data is created for a certain transfer program or with a certain sender structure. You need to have made the appropriate Customizing settings for this.
Procedure
1. Choose the appropriate menu path. The system displays a dialog box.
2. Enter the name of an existing Transfer program and choose Continue.
The system displays the screen Edit sender records. The list displayed shows at first only an empty data record.
3. Editing data records:
·
If you want to create a
new file using test data, choose File ® File name
® Physical. Enter a name for the file. Choose
Edit to insert further records,
either as new ones or copies. To create the test data, select one or more data
records and choose 
Edit
record.
·
If you want to change an
existing file, choose File
® File
name ® Physical
or Logical, and enter the name of
the file you want to change. Choose Read
file. The system displays all of the data records in the list. You can
navigate within a data record by using the arrow keys on the application
toolbar. The data in the current cursor position will be offset. To get a
detailed display or to make changes, choose Edit record.
4. In the following screen, enter the test data in the Contents column.
If you are creating or changing more than one record, you can switch between the different records by using the arrow keys in the application toolbar.
The three columns to the left of the table, B (beginning), M (middle), and E (end), rearrange the rows. This makes it easier to enter data if the sender structure has a lot of fields, but you do not want to enter data into all of them. You cannot save these settings. The next time you call up the screen, the fields will be displayed in their normal order again. When you are switching between records, however, the settings remain the same.
5. To save your newly created or changed data, choose Write selected objects in the previous screen. All of the selected records are then saved.
Result
The files are written to your application server. The data is stored in uppercase letters.
